Windows 7 - Change date on bootup possible?

[BiH115]

My father has a set of label making programs at work, and there seems to be some internal clock culprit where one program works off the Fiscal calendar, and the other one doesn't recognize it's the current week until at least a few days into the week (otherwise, it thinks it's last week). Apparently, it costs money for them to update and fix this, so here I am:

Is there a way, without messing with the bios, to run some script at startup where the internal clock thinks it's one week ahead of time, each day?

Figured I'd ask, because I've never really heard of anything like that, and I don't mess with Windows very much anymore. Thanks in advance.

Powershell (included in Windows 7 and 8/8.1):

Set-Date (Get-Date).AddDays(7)

Save it as 'setdate.ps1' or whatever, and use task scheduler to run "c:\windows\system32\windowspowershell\v1.0\powershell.exe" at log in with the file as an argument, and check the 'run as admin' box. Might want to turn off the time synchronize service as well, in services.msc.

This worked by the way, sorry for the late reply. Thank you.
