Java Instant ofEpochMilli() method

The ofEpochMilli() method of Java Instant class is used to obtain an instance of Instant using milliseconds from the epoch of 1970-01-01T00:00:00Z The seconds and nanoseconds are extracted from the specified milliseconds.

Syntax

Parameters

epochMilli - The number of milliseconds from 1970-01-01T00:00:00Z

Return

An instant, not null.

Exceptions

DateTimeException - If the instant exceeds the maximum or minimum instant.

Example 1

import java.time.Instant;
public class InstantOfEpochMilliExample1 {
   public static void main(String[] args) {
      Instant instant = Instant.ofEpochMilli(10000);
      System.out.println(instant);   
   }
}

Output:

The output will be like this.

1970-01-01T00:00:10Z

Example 2

import java.time.Instant;
public class InstantOfEpochMilliExample2 {
  public static void main(String[] args) {
    Instant instant = Instant.ofEpochMilli(123123123123L);
    System.out.println(instant.getEpochSecond());
    
  }
}

Output:

The output will be like this.

123123123

Example 3

import java.time.Instant;
public class InstantOfEpochMilliExample3 {
public static void main(String... args) {
    Instant i = Instant.ofEpochMilli(System.currentTimeMillis());
    System.out.println(i);
}
}

Output:
