Here are proposed time zone package changes, with summary information followed
by the actual changes. If no problems are found, these will appear on the
ftp site in nine days.
--ado
* zic.c
Do not end a binary file with a POSIX-style time zone string
for locations that end up in permanent DST
(thanks to Andreas Schwab).
* asia
Arbitrarily cut off Dhaka DST at end of 2009
(so that a POSIX-style time zone string can appear in the
Dhaka binary file, and for the benefit of systems with old
glibc reimplementations of the time zone library that don't
handle permanent DST correctly).
Note that another change will be needed once the real end
date for DST in Dhaka is known.
* africa
Change Mauritius to reflect that 2008-2009 DST experiment
is not repeated (and to change end of DST in 2009 from
2:00 standard time to 2:00 local time)
(thanks to Steffen Thorsen).
* europe
Update URL for Directive 2000/84/EC on summer-time arrangements
(thanks to Colin Watson and Ian Jackson).
* leapseconds
Change "no leap second" comment (no leap second at end of 2009).
* tz-art.htm
Add notes on "A Matter of Life and Death"
(thanks to Dave Cantor).
* tz-link.htm
Remove seemingly obsolete public.planetmirror.com/pub/timezone
link (thanks to Nathan Stratton Treadway).

+ In the 1946 "A Matter of Life and Death,"
+ there is a reference to British Double Summer Time.
+ The time does not play a large part in the plot;
+ it's just a passing reference to the time when one of the
