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());    }} |
Output:
Offset Time:17:52:49+03:45
