Question

What is the best way to convert hours into the time.

Lets say 5 hours and current time is 9:17am

Now if I run the app the time should be 0417 (am)

Thanks

A sequence to do that based on current time:

Calendar cal = new GregorianCalendar();
cal.set( Calendar.HOUR_OF_DAY, 9 );
cal.set( Calendar.MINUTE, 17 );

cal.add( Calendar.HOUR_OF_DAY, -5 );
System.out.println( cal.getTime() );
