Parallels: Vista clock unsynchronized

My clock in Vista keeps jumping ahead (which screws up time stamping). Even if I go into the options and change it to the real time, it jumps 7 hours ahead less than a minute later. When I restart parallels, it is wrong then also.

I made sure "synch with guest OS" was unchecked in parallels option as a google search recommended, and I also made it desynch with the internet, as a google search recommended.

Any idea?
