Faking time without changing Windows system clock

Does anybody know of a Windows tool to report fake dates/times to a process?

Apparently there are Linux programs that can be used to test how the software will react in the future / in a different timezone or to trigger scheduled tasks without actually modifying the system clock. Are there such programs for Windows?

Why does my computer clock show the wrong time?

When your computer clock is off by exactly one or more hours, Windows may simply be set to the wrong time zone. Even if you fix the time manually, Windows can reset itself to the wrong time zone once you reboot.

RunAsDate can do this.
