What is Epoch time in Java?



Replied on August 29, 2019
An epoch is an instant in time used as an origin of particular calendar era. Epoch is a reference point from which a time is measured.

In java.time package, we have classes to handle epoch.

1. ChronoLocalDateTime. toEpochSecond()
Converts this date-time to the number of seconds from the epoch of 1970-01-01T00:00:00Z.

2. LocalDateTime.ofEpochSecond() : 
Obtains an instance of LocalDateTime using seconds from the epoch of 1970-01-01T00:00:00Z.

3. LocalDate.ofEpochDay(): 
This returns a LocalDate with the specified epoch-day. The EPOCH_DAY is a simple incrementing count of days where day 0 is 1970-01-01.

4. LocalDate.toEpochDay():
The Epoch Day count is a simple incrementing count of days where day 0 is 1970-01-01 (ISO).
