![]() Instant The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction). Getting current time in UTC/GMT is a simple one-liner Instant instant Instant.now () That Instant class is the basic building block in java. Just run above program as Java Application in Eclipse IDE and you are all set. java.time The modern way to do this is using java.time classes. LocalDateTime localDateTime = instant.atZone(defaultZoneId).toLocalDateTime() ZoneId defaultZoneId = ZoneId.systemDefault() Log("Current Time in Epoch: " + epochTime) getTime() returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. parse() parses text from the beginning of the given string to produce a date.ĭate date = crunchifyFormat.parse(currentTime) String currentTime = crunchifyFormat.format(today) ![]() format() formats a Date into a date/time string. ![]() SimpleDateFormat crunchifyFormat = new SimpleDateFormat("MMM dd yyyy HH:mm:ss.SSS zzz") Summer time difference: int dstOffset cal. Constructs a SimpleDateFormat using the given pattern return The UTC date (the local datetime + the TimeZone offset) in milliseconds. param localDate The local datetime to convert to a UTC datetime, in milliseconds. This function performs that conversion using the TimeZone offset. In this tutorial we will go over simple simple steps on how to convert current time to Epoch time.ĭate today = Calendar.getInstance().getTime() /Since all dates from the database are in UTC, we must convert the local date to the date in UTC time. Getting current time in UTC/GMT is a simple one. Getting back to the focal point, ZoneOffset is a representation of time-zone in terms of the difference between GMT/UTC and the given time. package to supplant the old /Calendar classes. Lets get the current OffsetTime with 2 hours of offset: ZoneOffset zoneOffSet ZoneOffset.of ( '+02:00' ) OffsetTime time OffsetTime.now (zoneOffSet) 4. SimpleDateFormat is one of the most important. Wondering how to convert time to your user’s local time dynamically? Well, using Java’s getTime() returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. Java 8 brings an excellent new java.time.
