OffsetTimeDemo.java

import java.time.OffsetTime;
import java.time.temporal.ChronoUnit;

public class OffsetTimeDemo
{

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

        /*
         * Parameters:
         *
         * amountToSubtract - the amount of the unit to subtract from
         * the result, may be negative
         *
         * unit - the unit of the amount to subtract, not null
         *
         * Returns:
         *
         * an OffsetTime based on this time with the specified amount
         * subtracted, not null
         */
        OffsetTime offsetTime2 = offsetTime1.minus(2, ChronoUnit.HOURS);
        System.out.println("offsetTime2   = " + offsetTime2);
       
       
        OffsetTime offsetTime3 = offsetTime2.minus(20, ChronoUnit.MINUTES);
        System.out.println("offsetTime3   = " + offsetTime3);
    }

}

Output

offsetTime1   = 09:58:11.901+05:30
offsetTime2   = 07:58:11.901+05:30
offsetTime3   = 07:38:11.901+05:30
