LocalTime atOffset() method in Java with Examples

Last Updated : 03 Dec, 2018

The atOffset() method of a LocalTime class is used to combine this time with an offset object to create an OffsetTime object. All possible combinations of time and offset are valid.

Syntax:

public OffsetTime atOffset(ZoneOffset offset)

Parameters: This method accepts a single parameter offset which is the offset to combine with LocalTime Object, not null.

Return Value: This method returns the offset time formed from this time and the specified offset, not null.

Below programs illustrate the atOffset() method:

Program 1:

// Java program to demonstrate 
// LocalTime.atOffset() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a LocalTime Object 
        LocalTime time 
            = LocalTime.parse("16:12:49"); 
  
        // create a ZoneOffset object 
        // with 7200 sec means 2 hours 
        ZoneOffset offset 
            = ZoneOffset.ofTotalSeconds(7200); 
  
        // apply atOffset() 
        OffsetTime offsettime 
            = time.atOffset(offset); 
  
        // print LocalDateTime 
        System.out.println("Offset Time:"
                           + offsettime.toString()); 
    } 
} 

Output:

Offset Time:16:12:49+02:00

Program 2:

// Java program to demonstrate 
// LocalTime.atOffset() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a LocalTime Object 
        LocalTime time 
            = LocalTime.parse("17:52:49"); 
  
        // create a ZoneOffset object 
        // with 3 hours 45 minutes 
        ZoneOffset offset 
            = ZoneOffset.ofHoursMinutes(3, 45); 
  
        // apply atOffset() 
        OffsetTime offsettime 
            = time.atOffset(offset); 
  
        // print LocalDateTime 
        System.out.println("Offset Time:"
                           + offsettime.toString()); 
    } 
}
