I had a similar problem when using Debian testing. Basically, your 
problem is having two OSs thinking that they have sole control of the 
time. For example, if like me, you live in the UK, there is that crazy 
thing known as British Summer time. Because of that, you have to tell 
your computer that its timezone is in fact not GMT but Europe->London. 
This is because the time in the UK is only GMT whe summer time is not in 

Your choices are: either turn off time zone automattically changing the 
system time in one of the two OSs (preferably in windoze...)  or 
preferably set Ubuntu to London time, not GMT. That should then work.

The file that has the information of the timezone is /etc/timezone. You 
cam edit it (I think) or use dkpg to find out what package owns it and 
use the right package instead.
