dpkg-reconfigure -plow tzdata
as root which will allow you to set the global timezone data for your machine.
That way you don't necessarily have to adjust adjtime and can choose which timezone you're in which will
also sort out the DST "stuff".
Reset the clock using the date command to set the time.
to set the time in the hardware clock which should then be correct for Windows and Linux.
Myself, I keep computers set to UTC all year round.
