We have the code for windows (GetTimeZoneInformation, as used in the 
file routines for the DST fix) but I can't think of an easy way to make 
that work cross platform...

Standard Unix TZ format is supposed to be like 
GMT0BST1,M3.5.0/01:00,M10.5.0/02:00 which I reckon you could derive from 
the windows timezone information, *however* OS support for the format 
varies wildly, even though it's been standard since 1996 or 
thereabouts..  Win32 of course does not support that format...
