Can anyone point me to a utility package or other source for Date & Time Calculation? I believe someone had implemented the DATECALC EXEC, but can't seem to find it anywhere. Windoze platform...
What sort of date/time calculation are you after?
With Regina 3.3 you can use the 'T' option to DATE and TIME BIFs. The T option gives you time as a Unix time_t; the number of seconds since 1 Jan 1970. This make it easy to to do date and time calculations. (Just remember to set NUMERIC DIGITS 12)
I get a text file with the date and time already in their format. I read the file, parse line-by-line, and need to do some math on the dates and times, but can't convert them to T (or anything else). I had begun a subroutine, but thought there *must* be something like DATECALC around already. I remember it even checked for leap years, etc...
Please be more specific: what format do you recieve the date and time in? (is it mm/dd/yy? or dd/mm/yy? or ccyymmddhhnnss? etc)
What calculations do you need to perform (add/subtract days/hours to their number? determine number of days/hours remaining? determine age of subject? etc.)
Do your calculations have to be in just days, or days and hours?
Any other details will be useful.
The data comes to me like this:

...but I can easily mass-change the delimiters if necessary. These are the various stages of tool maintenance activity, and I need to calculate :
Wait Time for Service
Troubleshoot & Repair
Wait for parts (could be weeks!)
If I can't find a workalike for DATECALC, I think I will wimp out and just add things up until I get to 999.9 hours (after that, who cares?) and just report everything in hours. I have written a short subroutine that will do that much without too much trouble.
