Calculates the time difference between two dates, cumulative length, accurate to seconds __ notes

 * * Calculates the time interval, accurate to seconds, and returns a string/public string caculateduration (date begindate, date EndDate) {	Long Begindatelong = Begindate.gettime ();
		The date type converts to a long number of milliseconds, used to compute long Enddatelong = Enddate.gettime ();
		Long Durationlong = Enddatelong-begindatelong; Long totalseconds = durationlong/1000;//Total number of seconds long secondsofday = 24 * 60 * 60;//The number of seconds in a day long Secondsofhour = 60 * 6 0; The number of seconds in an hour long secondsofminute = 60; Seconds a minute long = totalseconds/secondsofday;//Get the number of days long hours = (totalseconds% secondsofday)/secondsofhour;/ /remainder of the number of hours long minutes = ((totalseconds% secondsofday)% secondsofhour)/secondsofminute; Minutes in remainder long seconds = totalseconds% 60;//remainder return day + "days" + Hours + "hours" + minutes + "min" + seconds + "seconds"
	; }

Call:
	Date nowdate = new Date ()//Get current system time
	date errordate = Errorrecord.geterrordate ()//Get fault occurrence time
	String Duration = Otdrservice.caculateduration (errordate, nowdate)//time difference based on two dates, cumulative length
