  Conversion of absolute time to delta time? 
 The Question is:
 
Hello,
Is there any quick possibility to convert an absolute time to a delta time
(relative to another absolute time) without writing an entire command
procedure in DCL or a program in another language?
Thank you,
Mihai
 
 
 The Answer is:
 
  There are short DCL command procedures around that allow mathematical
  manipulations involving pairs of absolute times.
 
  Without such a procedure (or an equivilent series of DCL commands or
  equivilent program), one cannot directly calculate the difference
  between two absolute times.
