(sorry to bump a slightly old thread, but...)
This PC is a new DEll Optiplex 760 that shipped with Windows XP Professional. It had been set up on our network and was functioning as expected. I decided to test Windows 7 on this system, so I reformated the drive and installed 7 RTM fresh. I know the issue is not the battery becasue when I go into bios the time is correct.
I think I am having a similar issue on a 760. Windows 7 Ultimate (x64) RTM, on our domain, and the time is not working correctly. I noticed today that if I go to Adjust Date/Time, and select a different window, the time stops, and eventually proceeds to the next second (
not in one second intervals). If I select the Date and Time window, again, it will proceed to tick off the seconds, in proper intervals. The time never jumps in large segments (multiple seconds or minutes), only to the next second.
The time rarely syncronizes with our time server, so I made a shortcut to update the time when I need it:
Code:
C:\Windows\System32\net.exe time \\[our time server] /set /yes
The time worked fine when I had windows XP installed, so I don't believe it is a hardware (battery) problem.
I formatted the drive during Win7 install, so it would not perform an upgrade.
There are a couple of others testing RTM on our domain, I am the only one with x64 and the only one with a 760.
edit: interesting.... I just noticed, if I keep moving the mouse, or hold down a keyboard key, the clock continues to tick off the seconds, correctly... I think M$ has just made it so the user's all put in the same amount of work, based on mouse movement, and keyboard use!
edit2: updated bios, from a02 to a03, clock seems to be functioning correctly. Will post back later if this did not work (should have thought of that sooner...
