Everything on my system is running like I like it to with the exception of the system clock in windows 7. It got this way when I installed Ubuntu 11.04 on a separate SSD that has to be chosen in BIOS. The Ubuntu clock is correct but every time I switch from Windows to Ubuntu and back again the clock in Windows is exactly six hours fast. I have re-set the clock to the correct time but this happens every time. I know this is not a great problem but I am curious as to why this happens. Any insights? Thanks ...Quixotic47
