The toEpochSecond() method of LocalTime class is used to convert this LocalTime to the number of seconds since the epoch of 1970-01-01T00:00:00Z. The method combines this local time with the specified date and 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.
public long toEpochSecond(LocalDate date, ZoneOffset offset)
Parameters: This method accepts two parameters:
- date: It is the date which is to be used for epoch second calculation as the target date.
- offset: It is the zone offset.
Return value: This method returns number of seconds since the epoch of 1970-01-01T00:00:00Z. It may be negative.
Below programs illustrate the toEpochSecond() method:
LocalDate: 2018-12-29 ZoneOffset: Z Epoch Second: 1546114352
LocalDate: 1909-04-18 ZoneOffset: Z Epoch Second: -1915746591
