var endDate = new GlideDateTime('2020-4-21 00:00:00');
var schedule = new GlideSchedule();

schedule.load('08fcd0830a0a0b2600079f56b1adb9ae'); // loads "8-5 weekdays" schedule. ('08fcd0830a0a0b2600079f56b1adb9ae' is sysid of the schedule.)
var duration = schedule.duration(startDate, endDate);
gs.print(duration.getDurationValue()); // gets the elapsed time in schedule
