System time clock

hi all \
has anyone had trouble with the clock changing its time and date at random ? i run windows 7 on my main hard drive and linux kubuntu on a ssd drive and was wondering if this is the cause? i only noticed today when my security software would not update and when i downloaded a program and noticed the install date was the 01/ 11/ 10 and the time was 1 hour fast i have checked the time server and corrected date and time and reset.

Yep, same here. Though my setup is little different. I have dual booted Win7 and Ubuntu and on certain intervals, the system time changes for both the OS.

I'm guessing you've followed all the steps in the Microsoft article Set the clock. It could be a weak or failing CMOS battery.

I have done that as well. Its not the CMOS battery. Its something to do with the mysterious dual boot config.

It is because you are dual booting. Linux sets the hardware clock one way, Windows reads and sets it another way. Windows use local time, Linux is set by default to use UTC time. The hardware clock has no timezone information so...confusion.

kubuntu has the same as windows to change time but the time servers to choose from are not the same

From an Ubuntu forum:

To keep Linux from using UTC, right click on the clock > preferences > uncheck the UTC box. Or, if you don't have a clock you can edit /etc/default/rcS and change the line UTC=yes to UTC=no. If you need to change the time zone you can run sudo tzselect.

To log in as root and change the UTC settings, use the command:
gksu gedit /etc/default/rcS

Don't know if this will help or not.
