To find the time difference and date difference

To find the time difference from a date, use the following formula in the script

var timeDiff = Math.abs(date1.getTime() - date2.getTime());
                log.debug('timeDiff', timeDiff)
               

The formula to calculate the days

                var diffDays = Math.ceil(timeDiff / (1000  3600  24));
                log.debug('diffDays', diffDays)
