OffsetTimeDemo.java

import java.time.OffsetTime;

public class OffsetTimeDemo

{

    public static void main(String[] args)

    {

        OffsetTime offsetTime1 = OffsetTime.now();

        System.out.println("offsetTime1     = " + offsetTime1);

        OffsetTime offsetTime2 = offsetTime1.minusHours(1);

        System.out.println("Hour changed    = " + offsetTime2);

        OffsetTime offsetTime3 = offsetTime2.minusMinutes(10);

        System.out.println("Min changed     = " + offsetTime3);

        OffsetTime offsetTime4 = offsetTime3.minusSeconds(20);

        System.out.println("Sec changed     = " + offsetTime4);

        OffsetTime offsetTime5 = offsetTime4.minusNanos(50);

        System.out.println("NanoSec changed = " + offsetTime5);

    }

}

Output

offsetTime1     = 09:40:02.729+05:30

Hour changed    = 08:40:02.729+05:30

Min changed     = 08:30:02.729+05:30

Sec changed     = 08:29:42.729+05:30

NanoSec changed = 08:29:42.728999950+05:30
