ChronoLocalDateTime toEpochSecond() method in Java with Examples
The toEpochSecond() method of a ChronoLocalDateTime class is used to convert this ChronoLocalDateTime to the number of seconds since the epoch of 1970-01-01T00:00:00Z. The method combines this ChronoLocalDateTime with the offset passed as parameters to calculate the epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z. Instants on the timeline after the epoch are positive, earlier are negative.
default long toEpochSecond(ZoneOffset offset)
Parameters: This method accepts a parameters offset which is the zone offset.
Return value: This method returns long which is the number of seconds since the epoch of 1970-01-01T00:00:00Z, may be negative.
Below programs illustrate the toEpochSecond() method:
ChronoLocalDateTime: 2019-12-31T19:15:30 Passed ZoneOffset: Z Epoch Second: 1577819730
ChronoLocalDateTime: 2018-10-25T23:12:31.123 Passed ZoneOffset: Z Epoch Second: 1540509151
