WinNT not in sync with BIOS clock

By misterIT ·
I recently installed NT, and the NT clock does not keep in sync with the BIOS clock after I shut the lid (Suspend), and then re-open (Resume).

My BIOS clock runs correctly (NT gets the correct time from there when I restart)

see Knowldege Base Article:
http://support.microsoft.com/support/kb/articles/q139/4/ 52.asp?id=Q139452

"Windows NT updates its internal date and time every hour by reading the CMOS on the motherboard. In-between the one hour intervals, Windows NT increments its own clock approximately every 10 milliseconds."

Anyone know if this 1-hour time update interval can be reduced by a registry tweak? Or can I manually poll the BIOS for the time with some command ?

WinNT not in sync with BIOS clock

by Joseph Moore In reply to WinNT not in sync with BI ...

According to TEchNet article q232488:
"A Time Daemon in Windows runs approximately once each hour after the Windows starts. The Time Daemon compares the time in Windows with the time in the RTC. If the two times are more than one minute apart, Windows changes the time and date to match the RTC.

You cannot change the time interval for the Time Daemon to run. "

The suggestion was to run TimeServ.exe from the NT4 Resource Kit, but that won't help you either. That is the Win2k method of time sync, where you pull the time from a network time server (like the US Naval Observatory). On a laptop that is not plugged into a network, this method won't work for you.

Sorry. Not too helpful.

Thanks for the info, but I think the same could be done with:
"
C>net time \\COMPUTERNAME /set /yes
Current time at \\COMPUTERNAME is Wed-10-Oct-01 1:17 PM
The command completed successfully.
"

..but I need an offline solution. Maybe thereis some utility to poll the BIOS time ?

NT should keep pace with the BIOS clock. If it doesn't the first thing I'd look at is changing the battery.

That could be a possibility. My battery is very low-performance, since I always use my laptop plugged in.
