[kmitnick]

hello folks, I am having Ubuntu 10.04, actually I am back to Ubuntu after 6 months of using Windows 7, anyway I have deual booted Win7 & Ubuntu, and every time I boot Ubutnu the clock is 6 hrs behind, I turned off the UTC

sudo nano /etc/default/rcS
...
UTC=no
...

but the clock is still missed up, so is it a bug as the Wifi Manager??

I solved the issue by synching windows and unix to use the same clock.

The problem araised due to the fact, that both windows and unix use the hardware clock. Obviously they both store the time there and there are ways to update the time in case it leaps for some seconds. Usually hardware clocks are not exact at all and can differ several seconds per day from the actual time.

That said, there are automatic update mechanisms in both operating systems that synch the hardware clock with a timeserver on the internet.

So, one of the OS (imagine which) did write the timestamp against all standards localized and not in UTC to the hardware clock. Unix then took the time and thought, it must be UTC and adjusted it to the timezone, which were several hours off the right time.

This is what I did to solve the problem:

I set the unix to automatic update the hardware clock synched to a remote server (there are for example these ones) and store the timestamp to the hardware clock (I think ntpclient is the program). On the other hand, I configured windows to not update the clock anymore (look into the clock window that opens when double clicking the taskbar clock and disable that NTP thingy).

Well, that was it. Windows from now on is no longer the authority to decide what is written to the hardware clock and everything is fine. The reason I came up with this, was, that I saw in the BIOS that the clock was also there behind for several hours.
