The OS doesn't really "change the time in the BIOS" - but both Windows and
Ubuntu are setup to automatically update their times from the net, and
since all *nixes expect the system time to be in UTC, when you shutdown and
the system time gets saved back to the CMOS clock, it saves UTC, not local. 
Then Windows does the same thing and saves back local time.
