It was brought to this thread that this is old information, and you can
instead tell Windows to use the hwclock on UTC through a registry key
change.
Barring any weird windows bugs, this would be a rather superior choice,
but one should test how Windows deals with an UTC hwclock during DST
changes to be sure.
