No it isn't!
That is already set.
Changing RTC_OFFSET would require a summer kernel and a winter kernel!
But I suspect that everytime I load win98 it will advance the clock
another hour!

Actually I think the RTC isn't set until after some filestore has been found
(there is a sanity check ensuring that the time hasn't moved by more than
5 years) so maybe the offset could be in filestore?
