Difference between datetime x++

In this post I am going to show the difference between 2  utc datetime and it will return the Days,Hours,Minute,Seconds

 utcDatetime PreparedOn ;
 utcDatetime DispensedOn ;
 str diffTime ;
 int time;

if(DispensedOn !=utcdatetimenull() && PreparedOn!=utcdatetimenull())
 {
     time           = DateTimeUtil :: getDifference(DispensedOn,PreparedOn);
     diffTime    = strFmt('%1d:%2h:%3m:%4S',(time div 86400),((time Mod 86400) div 3600),((time Mod 3600) div 60),((time Mod 3600) Mod 60));
  }
