Re: Finding the Elapsed time between two date fields

Andy,

not sure if you really meant *MDY for your fields, but i did something very
similar just recently.  here is what i have:

 *time stamps:

D $BegTime        S               z
D $EndTime        S               z

 *elapsed time datastructure:

D                 ds
D $Elapse                        7s 0     inz
D  $HHH                          3s 0     inz overlay($Elapse)
D  $MM                           2s 0     inz overlay($Elapse:*next)
D  $SS                           2s 0     inz overlay($Elapse:*next)

 *set beginning time

C                   time                    $BegTime

<snip>

 * set end time, calculate elapse time

C                   time                    $EndTime

C                   eval      $HHH = %diff($EndTime:$BegTime:*h)

C                   eval      $MM = %diff($EndTime:$BegTime:*mn) -
C                                   ($HHH*60)

C                   eval      $SS = %diff($EndTime:$BegTime:*s) -
C                                   (($HHH*3600) + ($MM*60))

 * $elapse now contains HHHMMSS between beg and end times.

----original message---------
I have two date fields *MDY with these values. '18:09:04' and '16:26:57'.
All I want to do is find the total elapsed time in hours,minutes and
seconds
between them.

I'm  using the SUBDUR like this;

EndTime    SUBDUR    StartTime    Hour:*H
EndTime    SUBDUR    StartTime    Minute:*MN
EndTime    SUBDUR    StartTime    Second:*S

Hour,Minute and second are part of a  6,0 data structure. When I put my
program in debug my 'elapsed' variable contains 010227. I suspect its
because of negatives I'm getting the minutes and seconds the way I am.

What am I missing here? (Should I be doing this differently then SUBDUR?)
