DATE$ function

[SMcNeill]

Or set Date$="01-01-1980" and see when Windows sycns with the internet.

If you go into the registry, hunt for:  HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\W32Time\TimeProviders\NtpClient.

Right click on the SpecialPollInterval key, then click Modify.

That's the time -- in seconds -- between when syncing happens. You can set the date for 01-01-0001, and it won't matter. In XXXXX number of seconds, you'll sync and reset the time, or else a vast majority of windows based software won't work properly anymore.
