Weekly Totaling of Time.

web · 2008-03-13

I now have "Total Time" as decimal datatype. But the values give me results like 12.97. I needed the result to be in time. I have been having problems in converting decimals to time.
Any idea please?
Thanks

How the heck is that possible?! :shock:

How do you display 11am - 2pm?

I would've by now just given in to an easy answer and stated dividing.

like take the .97 part w/ copystr or something, use some FORMAT's & EVLAUATES when needed & divide by 1.666 to give me the minutes. and throw it together in a text file vHour+':'+vMin

Sometimes I don't have the patients myself

I've been playing around with Times, Durations & DateTimes in the last few days on manufacturing project...but I've found it all boils down to some really simple math.

If you take a look at the documentation it shows that DURATION = DATETIME +/- DATETIME. But a variable of Duration Data Type is also synonymous with BigInt and stores time in milliseconds (1/1000th of a second).

So what I've done is delcare 4 Variables:

tmeStart (Time) - start time from user form
tmeEnd (Time) - end time from user form
durElapsed (Duration) - Duration datatype
iElapsed (Big Integer) - to be used for calculations
iRunTime (Integer) - Run Time for Journal line - in minutes

I'm going to skip a lot of logic I had in my form that tested whether the user had populated Start Time/End Time, whether they were within tolerances, etc. Then to Calculat etime Run Time in Minutes I used:

durElapsed := CREATEDATETIME(TODAY,tmeEnd) - CREATEDATETIME(TODAY,tmeStart);
iElapsed := durElapsed;
iRunTime := iElapsed/60000;

Remember that you must subract the Start Time from the End time to get a positive duration.

If you use iElapsed (or any other Big Integer) you can convert a duration to whatever you like using this conversion table:
1 Second = 1000
1 Minute = 60000 (or 60 * 1000)
1 Hour = 3.6 Million (or 60 * 60 * 1000)
1 Day = 86.4 Million (or 24 * 60 *60 * 1000)

So if you divide iElapsed by the appropriate value above you can turn a duration into whatever you like (hours, mins, seconds, etc).

durElapsed := CREATEDATETIME(TODAY,tmeEnd) - CREATEDATETIME(TODAY,tmeStart);
iElapsed := durElapsed;
iRunTime := iElapsed/60000;

where do you thing the above code could be placed. Time in, time out entry form or the report or the time sheet table.
Thanks.

I would put that code whereever you need to have the total elapsed time calculated - either the report or form that you're modifying.

i have placed it in both the form and the report but its not working. Here is my report maybe i am missing some logics:
