Tonga Daylight Savings Time ENDS...

[Pulu 'Anau]

Hi,

I'm a system administrator in a country that thinks it's funny to
constantly play around with the time.  To keep the story short, Tonga
decided to create daylight savings time to get a jump on everyone for the
new millenium.  The law was for 3 years, supposedly to get renewed.  It
wasn't.  Unfortunately, a good number of the systems I maintain (Debian
Linux and OpenBSD) would like to believe the government here is reasonable
and doesn't play around with stuff like this.  Ha!
Anyway, when they implemented daylight savings it took me a few hours to
find the zone files and recompile them, and I don't think the changes were
officially reflected (at least in Debian) for about a year.  I don't
really know where else to report this, but considering the vast amount of
history that's already available in the data files, I hope this mailing
list will work.
I've modified the australasia file from the data file as below.  I'm not a
zic expert so I hope it's appropriate.  It fixed the issue here, anyway.
Also, in the compiled file that was pre-existing on this system (Debian
3.0), the file for Tongatapu had a bunch of junk in it, basically a help
file for vi and some other binary data after the zoneinfo...  I don't know
if it's a debian thing or not, I'm not near the openbsd machines to take a
look at them... Just FYI...
If this file is going to explode on me at some later date, I'd really
appreciate if someone could write back and let me know.  Some of my
customers rely on this information to do some dialup internet/mail stuff,
and explaining they ought to complain to the government doesn't work
because most of them are the government.
