Given the code fragment:

ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 3, 0, 0, 0, ZoneID.of(''UTC-7''));

ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of(''UTC-5''));

long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1

System.out.println(''Travel time is'' + hrs + ''hours'');

What is the result?
