I have a simple problem nobody here seems to be able to solve (we're fairly
new to VMS) which is, how to display a file's age via DCL.  I can get
the revision date and time via F$FILE_ATTRIBUTES, but how do I subtract this
(which is a character string) from the current date and time (another string)
and end up with something meaningful (such as DELTA time format)?  I can't
see how to do it via F$CVTIME though I tried F$CVTIME(-RDT) and all it gave
me was midnight of today.  I can't believe this would be difficult in DCL
but it sure isn't obvious to me!
