First thing I would check is the CMOS battery if you have one or can

will have you right.

to prove or disprove, if op is interested is to pull mains for several
minutes, then boot to bios and check clock. no need for a full system
if clock is correct, not battery. if off by days, may be battery.
iirc, lithium cells and batteries should maintain level voltage over
around 3 years of load rating. after that time, voltage drops at a
i have seen lithium cmos batteries last over 5 years, but that was just
to see how long they would last.
i normally leave a system up 24/7/365 and only power down for service
or hardware change. running systems on apc ups makes for safe operation
because of ups feed back to system.
about 6 years ago, area lost utility mains and i ran home with a 40Kw
generator. i had to reset low voltage levels of ups so it would not
cycle to batteries when generator dropped in output.
