a different kind of "overclock"

I have been leaving my main PC running pretty constantly lately, and I have noticed several times in the last couple weeks that the time it displays in Windows sometimes gets 30 minutes or more ahead of real time. This morning I noticed again that it was a good 20-30 minutes "fast", so I manually synched it with time.nist.gov and went to work for the day. I looked at it just now, about 13.5 hours later, and noticed that it was 35 minutes ahead again!

Any ideas about why this would be happening? My system isn't OCed that much at all (Barton 2500+ @ 10x200, default vcore) and this either never was a problem before even on faster overclocks, or I just never really noticed it before somehow. Besides, I've never heard of CPU overclocking affecting the system realtime clock!
 
I've come across this before, but never was able to isolate the cause. My solution was to create a batch file that updates the clock via internet, and call this batch file every hour as a Scheduled Task.
 
I too have just started having this problem on my main desktop. How would I go about creating a batch file for this?
 
Download Cmdtime 3 from here. I unzip the file to C:\Program Files\cmdtime.

Batch file as follows:

C:
CD "C:\Program Files\cmdtime"
cmdtime3.exe /M:45 nist1-ny.glassey.com navobs1.gatech.edu ntp2.usno.navy.mil SYNC

That's it... Read the documentation for settings and syntax. Then create a scheduled task that runs this batch file hourly or whenever.

Wouldn't the clock slow down, rather than speed up if the CMOS battery were failing? That's been my experience.


heh, maybe its jsut REALLY slow so it LOOKS fast?

(kidding... JOKE) 😉
 
Not quite PC hardware, but a 10+ year old car that I'm driving has a digital clock that accelerates itself up to 45-50 mins faster. Maybe it's a faulty oscillator, or one that's seen too much parking under the sun. 😛

 
Well, it hasn't happened in a few days, interestingly enough. No, I haven't checked to see if the BIOS time is the same as the Windows time, since I just assumed they would be the same.
