Windows 7: Clock gains time with synchronized Internet Time set

Clock gains time with synchronized Internet Time set

The computer clock in my Windows 7 b7100 installation has been gaining about 30 seconds per day. I have tired setting the clock in Win7 to synchronize with and 4 different government servers. But with each set individually, the system clock never seems to be updated, and gains time every day.

In the past few weeks I've tried going to this registry:


And changing the default value of 604800 for the DWORD 'SpecialPollInterval' to 86400 (1 day) and 3600 (1 hour). But the system never synchronized the time after waiting 1 day and 1 hour respectively. I have to do it manually every day with Win7's 'Date and Time' > 'Interent Time' > Change Settings' > 'Update Now'.

This same system has never had any problem with synchronizing time with installations of Windows XP and Windows Vista in the past.

Does anyone have any idea what may be causing this?

I know it's a long shot, but have you checked your BIOS?

I'm able to set the time and date manually in BIOS. But there's nothing I can find there about automatically synchronizing the system clock with any Interent time server. That's only something I've seen available in the Windows OSs.
