Hello,

Below is resultant table with just the first and last records for each application.  How can I get the time difference between the first record (Start Time) and the last record (EndTime) for the same application id?

For example - AppID 1001 time difference is 0 hours, 2 minutes, 24 seconds.

Thanks!

DATETIMEs in SAS are stored as an integer number of seconds since 1/1/1960 0:00:00.  So, you can simply subtract the two values.  You can then format the result with a TIME format.

Data want;
set have;
by appID;
retain starting_time;
if first.appID then starting_time=starttime;
if last.appID then do;
duration=endtime-starting_time;
output;
end;
format duration TIME8.;
run;
