IF you can't trust the CMOS battery, then you need to get the time from the internet. There are a number of internet time servers which you can use: Google can help you, just look for NIST or NTP servers.

Setting the system clock though is a privileged operation - which means you need admin permissions to do it. The code is simple: http://msdn.microsoft.com/en-us/library/ms172517(v=vs.90).aspx[^] - but it may be more of a PITA that you want.

Me? I'd change the battery - they aren't expensive and old leaky batteries can do serious damage to the PCB!

actually the application is deployed,
.
client don't have internet connection, and also not ready to change CMOS cell.. :-(

Then:
1) He's stuffed. If he can;t access any clocks (internal or external) then he will have to continue to reset the time manually.
2) It's his problem. We - as developers - do not have responsibility for his broken hardware. Would he expect your software to "work round" a broken monitor or keyboard?

If they have a domain, the domain controller can be setup as a time server, and the client gets the "correct" time from that server during Windows startup.

Replacing the battery is a much better idea! :laugh:

True. But such are the customers we are used too, aren't they?

:laugh:
If one of my customers couldn't change (or get changed) the battery before it rotted away his PCB, he's not going to cope with setting up a time server! Or indeed tie his own shoes... ;)
