DATE$ function

[TerryRitchie]

Did you try "Run as admin"?  Windows really doesn't want folks to do much tinkering on date and time anymore, as they like to sync things all nice and neat via the web.  I honestly can't think of the last time that I've ever had to manually set the date and time on any of my PCs.

And even if you do get the software to change the date and time Windows would probably just resync it a short time later any way.

I know Windows Update will fail hard if the date/time in your computer is incorrect.

I can't think of any reason why I would want to have software change the date/time. I have not had to do that since the DOS days and PCs that didn't contain a clock chip like a Dallas and battery backup. If you're writing software that changes depending on the time of day (like bplus' banner) then a quick manual forced change to trick your software into believing the time/date is different is easily done and then removed before the final version.
