Java 8 – Convert Epoch time milliseconds to LocalDate or LocalDateTime

In Java 8, we can use Instant.ofEpochMilli().atZone() to convert the epoch time in milliseconds back to LocalDate or LocalDateTime

Epoch time to LocalDate


LocalDate ld = Instant.ofEpochMilli(epoch).atZone(ZoneId.systemDefault()).toLocalDate();

Epoch time to LocalDateTime


LocalDateTime ldt = Instant.ofEpochMilli(epoch).atZone(ZoneId.systemDefault()).toLocalDateTime();

P.S Epoch time is the number of seconds that have elapsed since 0:00:00 UTC on 1 January 1970

1. Epoch Time -> LocalDate || LocalDateTime

Get the current epoch time in long value and convert it back to LocalDate or LocalDateTime.

Java8ConvertEpoch.java

package com.mkyong.java8;

import java.time.Instant;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.ZoneId;

public class Java8ConvertEpoch {

    public static void main(String[] args) {

        long epoch = Instant.now().toEpochMilli();
        System.out.println(epoch);

        LocalDate ld = Instant.ofEpochMilli(epoch)
                .atZone(ZoneId.systemDefault()).toLocalDate();
        System.out.println(ld);

        LocalDateTime ldt = Instant.ofEpochMilli(epoch)
                .atZone(ZoneId.systemDefault()).toLocalDateTime();
        System.out.println(ldt);

    }

}
