Hi TZers,
Sorry if this has been asked before, but I couldn't find any
documentation on the rules of what should happen for the following
circumstances.
Here's the definition for Australia/Brisbane:
# Rule NAME FROM TO TYPE IN ON AT SAVE
LETTER/S
Rule AQ 1971 only - Oct lastSun 2:00s 1:00
D
Rule AQ 1972 only - Feb lastSun 2:00s 0
S
Rule AQ 1989 1991 - Oct lastSun 2:00s 1:00
D
Rule AQ 1990 1992 - Mar Sun>=1 2:00s 0
S
Rule Holiday 1992 1993 - Oct lastSun 2:00s 1:00
D
Rule Holiday 1993 1994 - Mar Sun>=1 2:00s 0
S
Zone Australia/Brisbane 10:12:08 - LMT 1895
10:00 Aus AE%sT 1971
10:00 AQ AE%sT
As the zone ends with AQ, and AQ does not have a "max" ending date, what
should Australia/Brisbane fall back to after 1992? I thought maybe in
this instance perhaps "Aus" as it's the one above it, but "Aus" seem to
oddly be specific to both World Wars. I also don't think that it should
then fall back to a GMTOFF = "10:12:08". That sounds awkward.
Thanks,
Alfie
