Richard,
here is an example in RPG-Free on V5R2. I'm not sure if it runs on earlier
releases.
The timestamps $StrTmStmp and $EndTmStmp hold the start and end time.
The result is the DS $TimDiff, which holds the difference with hours,
minutes and seconds.
Hope this is what you are looking for.
D DS
D $StrTmStmp Z Inz
D #StrDate D Overlay($StrTmStmp:1)
D #StrTime T Overlay($StrTmStmp:12)
D DS
D $EndTmStmp Z Inz
D #EndDate D Overlay($EndTmStmp:1)
D #EndTime T Overlay($EndTmStmp:12)
D #Diff 10I 0
D $TimDiff DS
D #DiffHours 7S 0
D #DiffMinutes 2S 0
D #DiffSeconds 2S 0
// Calculate time difference between start- and end date/time.
// Result fields are contained in DS $TimDiff
#EndDate=%date(20031011:*iso);
#EndTime=%time(060000:*iso);
#StrDate=%date(20031008:*iso);
#StrTime=%time(000000:*iso);
#Diff = %diff($EndTmStmp:$StrTmStmp:*seconds);
#DiffHours = #Diff/3600;
#DiffMinutes = (#Diff - #DiffHours * 3600) / 60;
#DiffSeconds = #Diff - #DiffHours * 3600 - #DiffMinutes * 60;

Betreff: calculate the difference between two time stamps in hh:mm:ss
good morning all,
I've searched the archives, but didn't find much help - I'm trying get
hh:mm:ss from the difference between two timestamp fields for displaying in
user readable format on a dspf.
Is there a way to do this without having to manually calculate hours and
minutes from seconds? - in other words, why can't I just subtract one time
stamp from another giving a time (t) data type?
I've tried several ways, but I'm coming up with incompatable types and
can't get it to compile. Am I missing something? a bif i haven't seen
yet?
Here is what I've tried so far:
D $StrTime S z
D $NewTime S z
D $WrkElapse S t
* (F1Elapse is 6S 0 dspf field)
---try number 1------
.....
C time $StrTime
.....
C time $NewTime
C eval $WrkElapse = $NewTime - $StrTime
C *hms move $WrkElapse F1Elapse
---try number 2------
.....
C time $StrTime
.....
C time $NewTime
C eval $WrkElapse =
C %diff($StrTime:$NewTime:*seconds)
C *hms move $WrkElapse F1Elapse
---------
thanks,
Rick
