Nothing, NetBSD knows all about DST and switches automagically.
I.e. the real time clock remains unchanged, but the value returned
by localtime() is suitably changed.

I can't swear on it, but I think NetBSD 1.1 has accurate DST
information for GB, otherwise you may want to copy your
/usr/share/zoneinfo/GB over to them.  But whatever time they show it
will not affect xntp syncing because, as I said, DST changes does
not affect the RTC, and it's those that are synced.

(Unlike that completely braindead scheme that Windoze uses.  If you
crossed from Europe to the US on a Concorde, changed timezone, edited
files, and used make on a Windoze laptop you would not get the right
files recompiled.  The same problems occurs if you work around DST
switch time.)
