Whatever is in the CMOS doesn't affect the kernel's system clock. That

This thread's been going long enough that perhaps it's worth restating
the clocks:

(1) hardware/CMOS/BIOS clock - only used at booting. Should normally be
UTC but some versions of Windows required it to be set in the local time
of the administrator.

Actually, (almost) all windows versions. W7 and W2k8 apparently accept utc,
with a hidden regedit variable.

I knew of this variable at least a year or two ago, but the documentation I
found of it was discouraging, warned of other problems.

(2) kernel's internal time - always UTC

(3) system-wide time - should be set to the time zone of the machine
that is running the system

(4) user time - individually set to the local time of each individual
user - defaults to the system time

All correct. :-)

N.B. That's for a computer kept in a single place, though possibly with
users around the world. I don't know what the convention is on a mobile
computer, though (1), (2) and (4) are unchanged.

For Linux, no change, you only need to change the timezone of the user, at
the place he is. For Windows, the clock changes, and the cmos too. A
nightmare if you double boot.
