Time Check

[shankle]

I'm checking in a program for the month of December.
If I change the date to 11-29-07 the program is
stopped.
If I change the date to 11-30-07 time 1:00 AM to 6:00
PM the program is stopped.
If the time is between 7:00 and 11:59 PM on 11-30-07
the program runs. Completely baffled
Thanks,
JPS

are you using local time or system time? because there is a difference between the two...

[shankle]

Thank you for responding Evlncrn8.
I used "GetSystemTime" in the program.
I guess I should have used "GetLocalTime".
Although I really don't understand the difference.

code..? :P


LocalTime is the time your windows clock says (hopefully the correct time for your particular time-zone.)
SystemTime is supposed to be GMT, from where everyone else should co-ordinate their time (zero meridian) -- where your local time will be something like GMT+6, or whatever your offset is (though SystemTime is actually LocalTime-6 instead, but that's just a cheat.)

SystemTime is supposed to be GMT

Or the new buzzword these days is UCT  Universal Coordinated Time.  Same difference though, but somebody somewhere had their 15 second claim to fame changing it.  Point being all my databases or most I should say have time stamps that are recorded in UCT.  Therefore if you look at a record in the Pacific time Zone that was posted at noon and then view that same record in Eastern time zone it will show 3:00 pm.

That way no matter where you are in the world the stamp will be relative to your time.
As Tedd says though, this is entirely defendant upon you system's regional setting being representative of your timezone.

I wrote a DateTime library to try and make working with dates and times easier. There is a help file included.
