Oracle tutorial: Date Time explaining how to use java.time.It’s a confusing trait of the outdated Date class that on one hand it represents just a point in time, on the other hand its toString method grabs the time zone setting of the JVM and uses it for rendering the string to be returned, thus giving you the false impression that you get different Date objects in different time zones when in fact they are equal. For example, it has different units of time like NANOSECONDS, MICROSECONDS, MILLISECONDS, SECONDS, MINUTES, HOURS, and DAYS. In Java 8, the LocalDateTime class contained a static method named ofInstant(Instant instant, ZoneId zone) that let you convert an Instant to a LocalDateTime by.

In Java, we can use the OffsetDateTime.parse (CharSequence text) static method to parse a String in ISO-8601 extended offset date-time format to a OffsetDateTime object as the Java code below. And at that point in time it was 21:15 in India and 11:45 on the East coast of North America. How to convert String to OffsetDateTime using OffsetDateTime.parse () method. In your case that point in time is Friday 9. so a count of milliseconds also denotes one point in time. The epoch is one point in time independent of time zone. Step 2: use the om (Instant instant) method to instantiate a new Date object from. Step 1: use the LocalDateTime.toInstant (ZoneOffset offset) method to convert the LocalDateTime object to an Instant object at UTC time zone offset. ZonedDateTime dateTime = pointInTime.atZone(serverTimeZone) In Java, with a given LocalDateTime object we can follow these steps to convert it to an UTC Date object. Since you want 21:15, specify the time zone for India: ZoneId serverTimeZone = ZoneId.of("Asia/Kolkata") Output from this snippet will be the same on all servers in all time zones: In this tutorial, we will show you few examples (ZonedDateTime (Java 8), Date, Calendar and Joda Time) to convert a date and time between different time zones. Instant pointInTime = Instant.ofEpochMilli(scheduledTime) Step 5 - Display the GMT date time formats Step 6 - Stop Example 1 Here, we bind all the operations together under the ‘main’ function. Step 4 - Define different date time formats using DateTimeFormatter objects. Import recommend you use java.time, the modern Java date and time API, for your date and time work. Step 1 - START Step 2 - Declare an object of LocalDateTime namely date.
