AW: calculate the difference between two time stamps in hh:mm:ss

[Werner Noll <werner.noll@xxxxxxxxx>]

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
