My guess is that it isn't fixable, but maybe you
have some ideas.

TIA.

This thread reminds me of an old Columbo movie.
As I recall, the murderer had reset his PC clock so that certain data
would be erroneously timestamped while his PC was used during his
absence -- thus providing his alibi later. I don't recall how Columbo
realized this bit of trickery had taken place, but, being Columbo, he
did. Nowadays, the culprit would need to remember to also keep the
machine from syncing with online time servers!

Not particularly helpful to the OP, just throwing it out there as an
amusing tangent.

More on point, I have an old W2K machine -- Abit KT-7 RAID mobo that I
had to recap -- that loses about 10mins every couple weeks. It isn't a
"mission-critical" machine and isn't online often, but I don't mind
occasionally resetting its clock.
