windows time change event

Hello all,

i need to detect when the time changes in windows. specifically, i am using an jni implementation in java to communicate with a short c program. the c should detect the time-change-event and passs it along to the java via jni. got everything working, excepted for the crucial part, i haven't been able to find the windows message (assuming thats how it can be detected) that notifies of such an event.

i am really hoping that someone knows something about this. i have been looking all over and there doesn;t seem to be anything usefull.

thanks.

Regards,

Nate

time change? the time changes every millisecond in a sense. if you really want to get specific, time doesn't stop changing! So what are you looking for, a message every second?

SetTimer()
KillTimer()
WM_TIMER

when i say "time change" i mean that the user has changed the date/time properties in windows. like, daylight-savings or a new time-zone. i am not interested in the actual time, merely the fact that the time was changed.

i hope i am being clearer. to reiterate, i want to know when the clock in windows is "set", not the passage of time.

thanks.

oh. interesting. I'm not sure that's possible with any api but there may be some odd hacked up way of handling it. I'll see if I can find a windows message though.

nope, sorry. I don't think windows notifies you about that.

FYB,

thanks allot for taking a look into this for me. i appreciate your time. i may end up polling, but its sooooo now ideal I doubt it will work well enough to implement properly.

thanks again.
