System clock switches from AM to PM or PM to AM by itself

This started after my last vacation. I left my computer off for about 12
days. When I returned and started it up I noticed the time was 12 hours
slow. I changed the time to the correct one using the atomic clock on my
wall, verified by my cell phone and by nist.gov website. I've had to change
the time about 10 times a day because it keeps changing itself to the
incorrect time, 12 hours in the past. The minutes seem to stay correct,
keeping in sync with my atomic clock but the PM/AM or AM/PM is always the
opposite.

I've changed the time in BIOS. I've changed the time in command prompt.
Both times using military time. I can't find how to change my windows lock
to 24 hour mode to maybe fix this but that's not what I need.

I've run 2 anti-spyware programs and neither found any issue I wasn't
already aware of (such as some programs starting when windows does, which I
need them to). I didn't install or remove any programs before or after
shutting the computer down for that 12 day period.

I've changed the CMOS battery. The one I took out has perfect voltage as
does the new one.

I've unchecked 'auto adjust for dst'; sync with windows and/or time.nist but
it won't sync. When it did sync a day after this issue started, it synced 12
hours slow.

My PC is custom using AMD Athlon 64 X2 Dual 4600+ at 2.4GHz with 2GB RAM.
I'm running WinXP SP2 Home.

** I am now looking at my system properties and it shows my processor is at
1.00GHz. This may be my issue. It's a fairly new processor and I haven't
seen it show that before, it usually said 2.4 GHz **

Does anyone have a clue why my clock is so off or if the 1.00GHz issue on
system properties for my processor could be the issue? This has been bugging
me for 2 weeks.

I figured out the issue was with my Davis Vantage Pro 2 Weather Station
having the wrong time. Once I changed the time to the correct one the issue
went away. Just to be certain I changed the time to wrong again and the
problem started up again.
