Java Program to get Epoch seconds from Instant

Create an Instant and get an Instant using milliseconds passed as parameter from the epoch of 1970-01- 01T00:00:00Z. This is done using ofEpochMilli():

Instant instant = Instant.ofEpochMilli(342627282920l);

Now, get the Epoch seconds from Instant:

instant.getEpochSecond();

Example

import java.time.Instant; public class Demo {    public static void main(String[] args) {       Instant instant = Instant.ofEpochMilli(342627282920l);       long res = instant.getEpochSecond();       System.out.println(res);    } }

Output

342627282
