The problem is by some weird way the clock got out of sync by about 1hr during daylight switch on one of the computers I run, and I need a reliable way to get passage of time (I don't need date/time, just the passage of it) for different internal operations in the program.

Looking for another clock already living there somewhere in the same
PC hardware isn't going to fix it.

You need to disable CMOS daylight savings time swithing in the BIOS,
so that it doesn't jump the reported clock value on you.
