Sara:
COMPUTE timegap =End_time - start_time.

gives the difference in seconds. You can calculate up to larger
intervals-- 86,400 seconds per day for e.g.

Or you can use DATEDIFF to get standard date units.

COMPUTE timegap = DATEDIFF(end_time,start_time,"months").

the help file says valid date units are
Years
Quarters
Months
Weeks
Days
Hours
Minutes
Seconds

Subject: Computing time spent

Hey everyone -

This is probably easy to do but I seem to be stumped (it is Friday after
all).  I have a variable of start time on a task and another variable
that is finish time.  I want to compute how much time they spent on the
task from these variables.  How would I do this?  I would prefer syntax
but I'll take what I can get.
