Hi Larry,
I know PC clocks are not all that accurate, but we're talking seconds per month. Needing to update a clock more often than that probably isn't due to the PC hardware. I've never had one be off this much unless the clock battery was dead, and any PC new enough to run Win-7 isn't going to have that issue. I would suspect that there is a some software you are running that is messing it up. Back in the DOS days, this was a common occurrence, and I'm surprised to hear about it under something more modern, but my gut feel tells me that is what is happening.
Maybe a device driver or something else low-level. Try booting something else (a "Live" CD of Linux, for example) to prove the hardware is good. Go back to Windows piece by piece. If you can figure out which it is, then this whole idea of applying bandaids can go away.
Just a thought,
Greg KO6TH

Even though Larry doesn't want to play with the registry it is IMHO the fastest and easiest, and, you don't have someone else' utility doing exactly that automagically for you.
In WIN7 I've done...
HKLM\System\CurrentControlSet\Services\W32time\TimeProviders\NTPClient and changed SPECIALPOLLINTERVAL to a decimal 3600 or whatever you want.

Hi Larry,
run regedit and change the update interval
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\Config
change UpdateInterval to 3600 (decimal) -> every hour

Hi Larry,
Time synchronization is scheduled in the 'Task Manager' of Win 7. Open 'Task Manager' and look for the item and edit it. Thanks for bringing this to my attention as I just upgraded (?) to Win 7. I set mine to sync at startup as I turn the PC off at night. My tracking software (Nova) also does it when it is started. Also updates Keps.

My PC's clock keeps getting off by enough to cause problems on near overhead passes. I've seen it off by more than 30 seconds. It is using Internet synchronization, which happens once a week. Is there a way to force Windows 7 to automatically update clock more frequently than once per week. Please don't tell me to monkey with the Windows Registry. I know PC clocks are notoriously inaccurate, but this is
ridiculous.
