If it's all the same to someone, and just want some reason to tip one
way or another, I'd go with modifying Windows. UTC actually makes
sense to store in a sufficiently complex system's hardware clock;
local datetime doesn't.

As I live in France, where there is DST change, localtime is absolutely a no-go. Too many
question marks when a system boots, the first one being a question the system cannot
answer easily: In which state the hardware clock is? Does it reflect current localtime?
And this question cannot be answered before having access to a time server. The rtc is
therefore totally useless, as we cannot trust it.

Surely off-topic, but I guess even Windows cannot handle dst correctly for the same reason.
I was thinking about a dual-boot machine: During the boot, a machine has no way to know
in which state the hardware clock is. I say dual-boot, because there could be ugly hacks on
a single system machine (like writing something in registry when the change is applied).
I suppose this is the way they do.


2 + 2 = 5, for very large values of 2.
