OffsetTimeDemo.java

import java.time.Duration;
import java.time.OffsetTime;

public class OffsetTimeDemo
{

    public static void main(String[] args)
    {
        OffsetTime offsetTime1 = OffsetTime.now();
        System.out.println("offsetTime1           = " + offsetTime1);
       
        Duration duration = Duration.ofHours(2);
        System.out.println("duration = "+duration);

        /*
         * Parameters:
         *
         * amountToSubtract - the amount to subtract, not null
         *
         * Returns:
         *
         * an OffsetTime based on this time with the subtraction made,
         * not null
         */
        OffsetTime offsetTime2 = offsetTime1.minus(duration);
        System.out.println("offsetTime2           = " + offsetTime2);
    }

}

Output

offsetTime1           = 10:08:03.779+05:30
duration = PT2H
offsetTime2           = 08:08:03.779+05:30
