Bangladesh is
applying DST this 20.th.of June. In file tzdata2009i this is the attempt to
implement it:
Rule Bang 2009 only - Jan 1 0:00 0 -
Rule Bang 2009 only - Jun 20 0:00 1:00 S
Now that doesn't make sense to me at all. Bangladesh has
not had anything close to "DST" since 1951, and then we zero-set DST January
1st. 2009? Then after implementation of DST next Saturday we leave it dangling
for the next millenium? Probably this is really just a "typo"
for
Rule Bang 2010 only - Jan 1 0:00 0 -
Rule Bang 2009 only - Jun 20 0:00 1:00 S
So Bangladesh
leaves DST with year end of 2009, since we have no authoritative information.
But this is not a very good guess in my opinion, in fact Steffen Thorsen
mentions semi-authoritative information:
"On another note, Bangladesh's
minister for power said earlier in 2009 that the new timing might continue until
the end of September. Timeanddate.com will provide an update on the DST end
date when it becomes available."
Any guess in the end
of September seems better to me, or October 1.st. 2009 at
0:00?
... perhaps this was
why Dave Rolsky's test cases were blowing up? :)
