• Localdatetime now now() var longdt: Long = getString(datetime). As for ZonedDateTime. A dependency injection framework is one way to achieve this: public class MyBean { private Clock clock; // dependency inject Why do you not simply use directly LocalDateTime as parameter type this way: LocalDateTime start = new LocalDateTime(2016, 10, 4, 17, 45); LocalDateTime end = LocalDateTime. now(). Current LocalDateTime localDateTime = LocalDateTime . Syntax: public static LocalTime now() Parameters: This method does not accept any parameter. LocalDateTime date = java. forPattern("yyyy-MM-dd I am testing a functionality ABC that uses LocalDateTime. The isBefore() method of LocalDateTime class in Java checks if this date is before the specified date-time. Date object. PowerMockito mock gets cleared after calling real method. The closest thing is the Clock object. Long answer: A LocalDate is an object representing a year, month and day, and those are the three fields it will contain. toString(); System. format(DateTimeFormatter. withNano(0) and truncatedTo(ChronoUnit. nanoTime() is less about precision but more about accuracy. This will query the system clock to obtain the current date-time. Java Date Time - LocalDateTime now() example. now() method is used to obtain the current date and time from the system clock in the default time-zone. These classes supplant the troublesome old legacy date-time classes such as java. DTO includes Instant type field. Your input string is in standard ISO 8601 format. My current approach is to use DateTime. now method, the JVM’s current default time zone is implicitly applied. but while storing in DB it is not storing the actual date, it is storing some binary type value in DB. For default format, it is simply converted from a LocalDateTime object to a string using a toString() method. now, the JVM’s current default time zone is implicitly used to capture the current time as seen by the people in the region of that zone. LocalDateTime date = LocalDateTime. Prokhorov's answer is correct, I just want to add a few points. I assumed it is because the second are zero, but I need the seconds. #now returns the current Date-Time using the JVM's timezone. format(formatter) 2. getDefault(); String zon Note that the expression System. And search Stack Overflow for many examples and explanations. time, the modern Date-Time API: If you want to get just date and time (and not the timezone information), you can use LocalDateTime. Never use LocalDateTime to represent a moment, a specific point on the timeline. LocalDateTime ldt = new LocalDateTime(); DateTimeFormatter dtf = DateTimeFormatter. LocalDateTime class, introduced in Java 8, represents a local date-time object without timezone information. SSS")); Wrong class. I am using Spring Runner and not PowerMock. UtcNow. Back to LocalDateTime ↑; LocalDateTime now() gets the current date-time from the system clock in the default time-zone. I'm attempting to use the new time API to make the code more update to date. using the system's default time-zone unless you specify a time-zone with it e. The documentation of LocalDateTime specifies the instance of LocalDateTime is immutable, for example plusHours. now(clock); On the test side I mocked the Clock. DateTime. tl;dr. Obtains a clock that returns the I am wondering if there is a way to get current milliseconds since 1-1-1970 (epoch) using the new LocalDate, LocalTime or LocalDateTime classes of Java 8. nowメソッドで現在日時を取得できます。 Java8で導入されました。Date and Time APIと呼ばれてい . now(ZoneId. now(); LocalTime localTime = localDateTime. 2015-07 public static LocalDateTime now Obtains the current date-time from the system clock in the default time-zone. The NOW() function returns the current date LocalDateTime timePoint = LocalDateTime. DISTANT_FUTURE. Month, now. class) (and of course your test runner should be @RunWith(PowerMockRunner. now()は、デフォルトのタイムゾーンを取得するとあるけど、実際どうなのかやってみました。ソースコードpackage test;import java. * import kotlin. LocalDateTime; DateTimeOffset. Specification is JSR 310. Now the tricky details: when you call the now() method (for either LocalDateTime or LocalDate), it uses the JVM's default timezone to get the values for the current date, and this value might be different depending on the timezone configured in the JVM. You can pass an instance of java. Now: var now = DateTime. Instead of mocking a static method (which is never a good idea really IMO) you can use the Clock feature offered by the java. getOffset(LocalDateTime. 591 Timestamp timestamp = new Description. What's the difference between LocalDateTime, Date and Calendar and why do we prefer LocalDateTime inst public static LocalDateTime now Obtains the current date-time from the system clock in the default time-zone. 1. class}) Include both the class to mock and the class using the mock LocalDate date = LocalDate. now() prefer LocalDateTime. systemDefault()) or even ZonedDateTime. This is a static method and returns an object of the LocalDateTime class. In this example, you will learn different The toString() method of LocalDateTime class is used to get the String representation of this LocalDateTime. I have a model object which includes LocalDateTime type field. You cannot. I can do public LocalDateTime now() { return LocalDateTime. getRules(). In the JVM I'm using, the default timezone is America/Sao_Paulo, and the local time here is 09:37 AM. How am I able to do this? var datetime = LocalDateTime. time framework is built into Java 8 and later. FromDateTimeUtc(time. You can specify the name-value pairs in any order, but the output is ordered as a default To get the current time in a specific time zone, we can use LocalTime. datetime. LocalDateTime#truncatedTo(ChronoUnit. You are using an Instant to get that milliseconds representation. now() gives the time in the format hh:mm:ss,nnn. ObjectMapper mapper = new ObjectMapper I'd like to mock both LocalDate. (Unlike LocalDateTime?, which would be. now (); // Create DateTimeFormatter instance with specified format DateTimeFormatter dateTimeFormatter = DateTimeFormatter . Basil Bourque Basil Bourque. This class provides the main application entry point for printing and parsing and provides common implementations of DateTimeFormatter: . To mock classes from JDK you need to prepare those classes for testing by using @PrepareForTest(LocalDateTime. now() it's giving me a NullPointerException pointing to some tzbd file which doesn't exist. now(clock) using Clock. time package and it represents both date and time information without timezone. Declaration. of("Europe/Oslo") instead as suggested in other answers. class,Validator. Obtains the current date-time from the system clock in the default time-zone. This method will return ZonedDateTime based on system clock with default time-zone to obtain the current date-time. now()); return How to mock LocalDateTime. Unfortunately, all existing answers have missed a crucial thing, Locale. LocalDateTime. minusDays(300); int days = Days. now() I get LocalDateTime in Java 8 with LocalDateTime. A java. now (Clock clock) method of a LocalDateTime class used to return the current date-time based on the specified clock passed as parameter. This Java SE 8 Date and Time document has a good overview about it. time framework, I want to print time in format hh:mm:ss, but LocalTime. now() uses a system default Clock. now() LocalDateTime next = ? I tried CronSequenceGenerator and its next() method but it uses java. One of the most useful classes in this API is LocalDateTime, for holding a timezone-independent date-with-time value. 2. This class is a date-time value without timezone information, so it is perfect for cases where timezone adjustments are not the priority. ; LocalDateTime represents a date and a time-of-day. * fun main() { //sampleStart // Converting a LocalDate and a LocalTime to a LocalDateTime currentLocalDateTime = LocalDateTime. Syntax: Parameters: This public static LocalDateTime now (ZoneId zone) Obtains the current date-time from the system clock in the specified time-zone. So, when converting a LocalDateTime to a java. Instant. time package added in Java 8. of(2020, 07, 05); @Mock private Clock clock; private Clock fixedClock; and used it as that: Note that LocalDateTime. LocalDate now = new LocalDate(); LocalDate past = now. Return value: This method returns the current time using the system clock and default time-zone. 99) for seconds fields. We can also plus or minus a certain amount of time in Kotlin using LocalDateTime, for example, Formatter for printing and parsing date-time objects. UTC) is a conversion call to ZonedDateTime as LocalDateTime does not have a zone. You can create a Clock object using any time you want (or from the System current time). Following is the declaration for java. now(Clock. atZone() simply assigns a time zone, it doesn't change the time. @Test void someTest(){ // I am testing a functionality ABC that uses LocalDateTime. Use LocalDate. toKotlinLocalDateTime() extension functions to convert between So you will now need to convert from a LocalDateTime that does not define a point in time, to a Timestamp that does define one, then pass the Timestamp to an API that may store it in a database column that again does not define an unambiguous point in time. now(); to invoke the static LocalDateTime#now() (note there are multiple now() functions provided, this makes it much easier to effectively use different time zones). now(); and if you have import java. private final static LocalDate WEEKEND = LocalDate. To use object mapper, you need register the JavaTime. ). Another alternative (specially if you want to change an already existing LocalDateTime) is to use the with() method. So I've written this code: java. But the now method uses a timezone or an offset to get the correct values for those fields. ofPattern("yyyy-MM-dd HH:mm") val current = LocalDateTime. Now, I want to generate the 'now' again from epochSecondNow: LocalDateTime class has a method ' ofEpochSecond(long epochSecond,long nanoOfSecond, ZoneOffset zoneOffset) ' which takes epoch second, nano of second and ZoneOffset as arguments. Syntax: public String toString() Parameter: This method takes no parameters. In the methode ABC i’am comparing an entry date with the LocalDateTime. There are probably millions of lines of code using the legacy class java. So LocalDateTime does import kotlinx. And because you haven't specified its type, the compiler infers LocalDateTime (so even if it were a var, it could still never be null). So we rarely use this class in most I want to mock the update method and I want to check if it returns false in validate method when the time is false. parse("2018-06-23T05:55:55"); LocalDateTime endOfDate = localDateTime . public static LocalDateTime now() Package Name: java. This is correct. now() to LocalDateTime. 5. PowerMockito is So parse it into LocalDateTime using DateTimeFormatter Then convert localDateTime into ZoneDateTime at zone Asia/Jakarta Finally convert zoneDateTime into GTM date time which is equal to UTC About java. ZonedDateTime is an immutable object that holds a date-time value to a precision of nanoseconds, a time zone value based on The LocalDateTime#toString by default omits second-of-minute and nano-of-second fields if they are zero. Instant and LocalDateTime are two entirely different animals: One represents a moment, the other does not. Furthermore, let's assume I generate my current time zone id as such TimeZone timeZone = TimeZone. In the methode ABC i'am comparing an entry date with the LocalDateTime. now() uses the system default Clock which is only guaranteed to have millisecond precision, but can use a higher resolution clock if one is available. getHour() + ":" + now. So in Java 8 something like below will do the trick (to format the current date/time), LocalDateTime. systemDefault()) so the reader knows in which time zone you get the time. Best practice for applications is to pass a Clock into any method that requires the current instant. LocalDateTime is the local date-time i. For Android Gradle Plugin 4. This is my code DateTimeFormatter formatter = DateTimeFormatter. This: LocalDateTime. This method is particularly useful for capturing the current To get the current date-time using the system clock and default time-zone, we can use the LocalDateTime. That's because the answer to the questions "What day is today?" and "What time is it?" java. 6. (VM is even worse since you don't have a physical clock and have to sync with the host) When your computer syncs this quartz The Java LocalDateTime API represents and manipulates a combination of date and time. It is equivalent to calling any of the following: DateTime. now() to represent the clock now. DateTimeFormatter of the modern API or SimpleDateFormat of the legacy API) is Locale-sensitive. now() because it represents a "now" date/time on this system, with no specific tz attached. getDays(); Never convert a LocalDate to a Java Date (two completey different beasts) if you are just dealing with dates. 6 Mock LocalDate. now() method When a programmer writes LocalDateTime. Much of the java. Using predefined constants, such as ISO_LOCAL_DATE; Using pattern letters, such as uuuu-MMM-dd; Using localized styles, such as long or medium; More complex formatters are LocalDateTime型からString型に変換. now(); } in the same class But then I have to write separate test cases for the class and it will work only for that class . Just like Instant, there are a number of static methods that let us supply various combinations of the date and time values: The now() method of the LocalTime class in Java is used to get the current time from the system clock in the default time-zone. time functionality is back-ported to Java 6 & 7 in the ThreeTen-Backport project, and further adapted to Android in the ThreeTenABP project. I want to do a select from table where date = TODAY, on mysql that would be where date > CURDATE(), how do I do this on a JPA named query? Starting from JDK 8, It's also possible e to leverage on the LocalDateTime method ofEpochSeconds: private LocalDateTime epochSecondsToLocalDate(long epochSeconds) { ZoneId zoneId = ZoneOffset. atZone(ZoneId. However LocalDateTime. Date for this purpose. ofPattern("yyyy/MM/dd HH:mm:ss"); LocalDateTime now = LocalDateTime. atZone:. withZoneSameInstant(ZoneId. With 'normal' dates I have no problem, but the LocalDateTime fields are converted to the following: " Now, you must get the correct format. now() This is my test: If you read the documentation, the javadoc of Timestamp. println(dateTime); }2. println(now. The argument passed into atZone() method should be an original (default in this example) time zone used to derive LocalDateTime, not the "to" zone the author probably intended to get out because Instant does not have a zone. ToLocalTime() DateTimeOffset. This returns a ZonedDateTime formed from this date-time at the specified time-zone. LocalDateTime. toLocalTime(); 4. now(); System. In the above program, the current date and time is stored in variable current using LocalDateTime. PCTime. We use new Date(), Calendar(). method(LocalDate. now(); String formatTime = now. By the way, be aware that LocalDateTime is inherently ambiguous. So they should use ZoneId. The class that handles both date and time, without a time zone, is LocalDateTime, one of the core classes of the Date-Time API. LocalDateTime class is part of java. LocalDateTime class, introduced in Java 8 The current date-time can be obtained from the system clock in the default time zone using the now() method in the LocalDateTime class in Java. systemDefaultZone())); 2. MAX); But in this section, we’ll analyze one I am working on Spring data JPA, I have created an entity in which I am taking a date as LocalDateTime (Java 8). The time values (hour, minute, seconds and milliseconds) are all set to zero. Returns: The function returns boolean value: if this date-time is before the As already stated in my answer, calling LocalDateTime. ofPattern("yyyy-MM-dd HH:mm:ss. How to remove T in my localDate? I need to remove the 'T' to match data in my database. The provided LocalDateTime is interpreted as the local date-time in the local time zone. Manually field setting like that; set( LocalDateTime. Then you can mock that method to return your specific instance - This would not seem practical if you're directly calling LocalDate. Valid values are numbers between 1 and 12 for the month, 1 through 31 for the day, 0 through 23 for the hour, 0 through 59 for minutes, and 0 through 59 (including decimals, such as 59. The toEpochSecond() method of a LocalDate class is used to convert this LocalDate to the number of seconds since the epoch of 1970-01-01T00:00:00Z. truncatedTo(TemporalUnit unit) method. now() and LocalDateTime. You don't need to cast to DateTime. public class Main Learn about the LocalDateTime class in Java, how to create its instances and other use cases such as parsing, formatting and adding duration and periods. if you run the following statement on a machine set with Europe/London timezone, it will show the date-time in GMT and if you run it on a machine set with Asia/Kolkata timezone, it will show the date By the way, I cannot imagine a case where calling LocalDateTime. The problem is I'm trying to use java8 time API, with LocalDateTime and everytime I'm calling LocalDateTime. sqlTimestamp for ormapping. Now. atZone(ZoneOffset. unit − the unit to truncate to, not null. It does not have a format, because different locales will have different formats, and it will make it more difficult to perform the operations that one would want to perform on a LocalDate (such as adding or subtracting days LocalDateTime now = LocalDateTime. format. It's not hard to agree LocalDateTime has no tz information, that's pretty much in the name. with(DayOfWeek. As such in US or some other countries - where week starts on Sunday - it may not work as you would expect - Platform specifics. class). The public static LocalDateTime now() Obtains the current date-time from the system clock in the default time-zone. Despite the often misleading name such classes like LocalDateTime or LocalTime have NO timezone information or offset. Should I use LocalDateTime while in DB or not, if not when should I use this java 8 date API. java. Year, now. The java. it gives a value equal to LocalDateTime. answered May 25, 2020 at 19:04. time. stub(PowerMockito. LocalDateTime localDateTime = val current = LocalDateTime. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface. e. systemDefault(); ZoneOffset zoneOff = zoneId. This instance is immutable and unaffected by this method call. And according to javadoc, passing a LocalTime to this method does exactly what you need:. Below programs illustrate the now() method of Now, for example, when a search for a date comes in, I have to convert from the requested date time to UTC, The entire point to LocalDateTime is to lose time zone info. I have a LocalDate that I need to convert to either a (Joda) LocalDateTime, or a java. toJavaLocalDateTime() and java. Time is represented to nanosecond precision. 999999999」。 I am using JodaTime 1. And over LocalDateTime. systemDefault()) since the system default time zone was used to The LocalTime class does not store time zone or daylight saving time information. To learn more, see the Oracle Tutorial. now() call in a non-static method of a class. The symbols used in its pattern print the text based on the Locale used with them. public static LocalDateTime now() Example. now(ZoneId): LocalTime localTime = LocalTime. daysBetween() is the answer. But sometimes this now() function returns the time to me in a format without seconds. If I have to use the same in integration testing where I am testing one complete API , how it will In this post, we look at date and time APIs introduced in Java 8, specifically the LocalDate, LocalTime, and LocalDateTime APIs, which are timezone independent. I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat. now(Clock) method, that is pretty test-friendly, as already suggested in comments - I'm having a small problem with formatting a Java 8 LocalDateTime in my Spring Boot Application. Syntax: This article shows few Java examples to get the current date time or timestamp in Java. The next step is to decide that "here the tz is UTC" and decorating the original object with it. You should never ignore this character, as you seem to be intending by the use of single-quote marks I'm looking to get the time from LocalDateTime (unless there is an easier way) with the format of HH:mm:a (12:34 pm) Which Date/Time formatter do I want to use? val sdf = SimpleDateFormat("HH: There are a few options you've: Wrap the LocalDate. It implements the ChronoLocalDateTime interface and inherits the object class. I now want to check that the item is within the last 30 days. Date keeps only the day, month and year values. I want to map LocalDateTime type field to Instant type field. differences in year, month and day, you'll get the start time 7:45:55 and the end time 19:46:45 (or 7:46:45 PM). That type cannot represent a moment, is not a point on the timeline, because it purposely lacks the context of a time zone or offset-from-UTC. As written, dateSentFormatted can't be null: you're setting it to the return from timeFormatted(), which returns a LocalDateTime, which is not nullable. Share. So you can use dependency injection to inject a Clock with a specific time: Number values for year, month, day, hour, minutes, and seconds fields. Now returns a DateTime value that consists of the local date and time of the computer where the code is running. MONDAY)) is locale-independent as it uses ISO-8601, therefore it always jumps backwards to last Monday (or stays on Monday in case date points to Monday already). It depends on what form of date / time you want: If you want the date / time as a single numeric value, then System. In ZonedDateTime class, there are three types of now() method depending upon the parameters passed to it. time classes. The time value of the returned calendar is truncated to milliseconds and the time zone is the current system default. LocalDateTime class represents a date and time without a time zone. time, the modern Java date and time API. MINUTES) sets the second-of-minute and nano-of I just looked at the code once more and it seems the website is wrong (Try calculating yourself). toInstant() - its javadoc clearly explains the implementation: This returns an The LocalDateTime object itself doesn't store the timezone information - it has only the date and time related fields: day, month and year; hour, minute, seconds and nanoseconds. It implements the ChronoLocalDateTime now(Clock clock) method of a LocalDate class used to return the current date based on the specified clock passed as parameter. Follow answered Feb 28, 2018 at 16:12. println(LocalDateTime. ofInstant(x. Using Calendar @M. minusDays(30) and I have a System. Timestamp:. Returns: This method returns a String value which is the String representation of this Further, LocalDateTime. Improve this answer. I thought LocalDateTime was the local datetime. 0+: Use Java Desugaring feature so you can use Java 8 Date library without any problem for API level lower than 26 too. Current Date and Time: It is convenient to get the current date and time, which is provided by the LocalDateTime class of the java. now() works perfectly on my system if I just open up a console project and run the code there. Syntax: @JinKwon I was merely refering to the fact that ZoneId. now() now() method of a ZonedDateTime class used to obtain the current date-time from the system clock in the default time-zone. now(); PeriodType ptype = PeriodType. Your Question makes no sense. println(Instant. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. System. This value is a delta from a UTC time-point, and is LocalDateTime is wrong class. From the Clock JavaDoc:. Learn to compare two LocalDateTime instances to find out which date represents an older timestamp compared to another. This method is derived from the Object Class and behaves in the similar way. public LocalDateTime plusHours(long hours) Returns a copy of this LocalDateTime with the specified number of hours added. This class is used to represent date (month-day-year) together with time (hour-minute-second-nanosecond) and is, in effect, a LocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. Parameters: hours - the hours to add, may be In this article Syntax DateTime. However, it seems the first LocalDateTime mock somehow doesn't work correctly if both are present. 0; public Calendar toCalendar() Returns a generally equivalent instance of Calendar. ofPattern ( "yyyy-MM-dd HH:mm" ) ; java. currentTimeMillis() is based on the system clock, which is, most of the time, based on a quartz clock inside a computer. valueOf (LocalDateTime dateTime) says:. This method requires no parameters and it The LocalDateTime. Days. atTime(LocalTime. DISTANT_PAST and Instant. If you remove ZoneOffset. It is equivalent to using LocalDateTime.

The known way is below: long What is the recommended way to create a LocalDate instance that represents "today". Date Time API is one of the biggest features of Java 8 release. util. Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded. Java 8 has a completely new API for date and time. So the difference between those two times is 12 hours, 0 minutes and 50 seconds and never 23 hours, 34 minutes and 12 seconds. LocalDateTime I am new in Mapstruct. It represents Summary: in this tutorial, you will learn how to use the PostgreSQL NOW() function to get the current date and time with the time zone. so I tried mocking call to LocalDateTime. The link in this Javadoc takes you to Clock. Current moment. I was expecting there to be a static "Now" or "Today" property in the LocalDate class, but there isn't. inLocalView(). The reason for this is I have figured out how to convert between a LocalDateTime and a java. The range of supported years is platform-dependent, but at least is enough to represent dates of all instants between Instant. Date and I would prefer not to convert LocalDateTime to Date and vice versa. I'm trying to avoid initialization of the library, which loads quite a large file of zones into it. currentTimeMillis() gives you that, expressed as the number of milliseconds after the UNIX epoch (as a Java long). If you want to change the time, you first have to specify the time zone of PCTime, e. format("HH:mm:ss") println "datePart : " + a LocalDateTime Since: 2. 16-2016a:. now() If we want to get the date in a certain format, we can apply the formatting with the help of the DateTimeFormatter class: val formatter = DateTimeFormatter. now() in java 8.

A Jodatime Localdate is a true "Calendar date", i. 3. Returns a datetime value set to the current date and time on the system. now() This is my test: I would make an interface called something like TimeProvider, then implement it with a function like `fun now() = LocalDateTime. ToUniversalTime()) This seems reasonable, but I want to be certain that this is completely reliable and doesn't have the Storing local dates in database is not a good idea because they are not instants of time, they are just localized presentation of time. The LocalDateTime class in Java is an immutable date-time object that represents a date in the yyyy-MM-dd-HH-mm-ss. This will query the system clock in the default time-zone to obtain the current date-time. now(clock). 0. You need to understand that LocalDateTime holds nothing but a date and a time-of-day. The Joda-Time project, now in How To Get Current Localdatetime In Java? To get the current date-time by using the LocalDateTime class object, we can use its now() method. time-package in Java-8) does not indicate that there is a timezone information in internal state of that class (here: LocalDateTime). println(timePoint); As per doc: The method now() returns the current date-time using the system clock and default time-zone, not null. ofPattern("yyyy-MM-dd'T'HH:mm:ss", Locale. LocalDateTime; then you only need. Overview. The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero. public LocalDateTime truncatedTo(TemporalUnit unit) Parameters. now() in unitTest. Scicrazed Scicrazed. Then use the TimeProvider everywhere. The prefix "Local" in JSR-310 (aka java. out. Let's say one week ago I generate a LocalDateTime of 2015-10-10T10:00:00.

I tried to use DateTimeFormatter: DateTimeFormatter formatter = I have a table with a DateTime column. Use the LocalDateTime. Demo: I have a situation where I would like to convert a DateTime to an Instant. LocalNow() as datetime About. isAfter(), isBefore() and The LocalDateTime is a new class introduced in Java 8 new Date and Time API. zzz format. now()`. It accepts a TemporalAdjuster as a parameter. Since the LocalDateTime in the UTC time zone, not the local time zone, the result is a time zone shift to JVM's default time zone. The classes LocalDate and LocalTime implement TemporalAdjuster, thus this method can be used LocalDateTime here because OP used it. So as written, there's no point in checking for null, and your My understanding is that you want to get the difference between those 2 dates and "break" it in terms of how many hours, minutes and seconds this difference is. Lacking the context of a zone/offset, a LocalDateTime cannot represent a moment. I believe the DateTime's Kind will be Local. All date. But a better way would be to avoid PowerMockito and design your classes in such a way that you can inject LocalDateTime into it. Follow edited May 25, 2020 at 19:27. now(); LocalDateTime nowInUtc = now. If you omit the date, i. yearMonthDayTime(); Period diff = new Period(start, end, ptype); See also the API of Joda-Time. That class represents a date with a time-of-day but lacks a time zone or offset-from-UTC needed to determine a point on the timeline. Instant represents a moment, a specific point in the timeline. The Z on the end means UTC, and is pronounced “Zulu”. Or should not use LocalDateTime for this purpose. From the Clock docs: Best practice for applications is to pass a Clock into any method that requires the current instant. now, you can bet they do not fully understand the necessary concepts. t 文章浏览阅读4. Date, these fields are lost. (Updated with Java 8). You've asked for a ZonedDateTime with the same LocalDateTime that you started with, but associated with a particular time zone.
