I'm sure someone'll tell me if this is initiating a discussion that is not
relevant to the tz mailing list, but it involves keeping track of time on

I'm not a Windows afficionado, and I doubt I'll ever be, but the
installation where I work now consists mostly of machines running one
version of Windows or another (at this stage mostly Windows NT 4).

As southeastern Australia (where I am) is starting daylight saving
considerably earlier this year than hitherto, I was concerned to know how
all our Windows boxes (especially our servers) could be made to behave
civilly in this circumstance. I asked a colleage this week about whether a
suitable patch or update from Microsoft (for NT) was possible, but he said
only service packs, which require bringing down the machine, were issued.
The only way we could see of getting around the problem was by setting the
machines' time zone to "(GMT +11:00) Magadan, Solomon Is., New Caledonia"
until the date when NT thinks daylight saving starts in our zone ("...
Canberra, Sydney, Melbourne", from memory). Your (Antoine's) mention of
"the Windows time zone database" makes me wonder whether that could be
edited instead.

I'd also be interested to know if anyone's worked out how to patch Mac OS's
Date & Time control panel (presumably its 'cty#' resource) to effect the
same adjustment.

Thanks for your attention.
