Hello,
i tried to set the system time from code in my program (Windows CE on picomod 6). I used the functions SetSystemTime and GetSystemTime of coredll.dll. Date and time will changed in the actual session but if i make a reboot the old date/time is set.
The same problem is if i use the windows date/time dialog!
What is the problem? Is it nessassary to change also entries in the windows registry? Or is there a spezial API/DLL?
Thanks for help.
Regards,
Alwin
Hello,
did you enabel battery for RTC?
Note, if you power off and there is no buffer battery connected to J1.Vbat the RTC is reseted while next power on.
Hello,
yes we have enabled a battery. The RTC shoud work because the time runs also if the system is off.
But i can not change the time...:-(

So what do you mean by "old date/time"?
And what do you mean by "But i can not change the time...:-("?
It seems to work according your post but after reboot date/time "disapears", so i assume battery does not work!
Hello hpb,
The RTC clock works fine but with a wrong date and wrong time. So i correct the date and time within my code (with SetSystemTime) in my program (or with the standard windows date/time dialog). Now the date and time ist correct.
If i now reboot the system date time will set to the (old) values before i made my changes (+ N minutes for the time i need for changes and reboot).

Hello,
very strange!
Which value has the "old" time?
Have you configured the time server (HKLM\services\timesvc)?
