The minusMillis() method of Instant class subtracts specified duration in milliseconds from this instant and returns the result as an instant object. This returned Instant is immutable.
Syntax:
public Instant minusMillis(long millisToSubtract)
Parameters: This method accepts one parameter millisToSubtract which is milliseconds to subtract.
Returns: This method returns the Instant after subtraction of milliSeconds.
Exception: This method throws following exceptions:
- DateTimeException: if the result exceeds the maximum or minimum instant.
- ArithmeticException: if numeric overflow occurs.
Below programs illustrate the minusMillis() method:
Program 1:
// Java program to demonstrate// Instant.minusMillis() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant            = Instant.parse("2018-12-30T19:34:50.63Z");          // subtract 64000000 MILLI_OF_SECOND        // means 64000 seconds from this instant        Instant returnedValue            = instant.minusMillis(64000000);          // print result        System.out.println("Returned Instant: "                           + returnedValue);    }} |
Output:
Returned Instant: 2018-12-30T01:48:10.630Z
Program 2:
// Java program to demonstrate// Instant.minusMillis() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant = Instant.now();          // current Instant        System.out.println("current instant: "                           + instant);          // subtract 36000000 MILLI_OF_SECOND        // means 36000 seconds from this instant        Instant returnedValue            = instant.minusMillis(36000000);          // print result        System.out.println("Returned Instant: "                           + returnedValue);    }} |
Output:
current instant: 2018-11-27T05:13:12.132Z Returned Instant: 2018-11-26T19:13:12.132Z
