2. For Lord Howe's daylight saving time, could we just report AEDT as it's the same time as Sydney, Canberra, etc? Oh yes. Will have to look how to do this. That would also eliminate H = Half hour saving. LH specific DST code would be needed for 1981 to 1984 when saving was one hour.
Some further thoughts on this: There are examples in the IANA time zone database where two areas observe the same offset from UTC for some time of the year, but still use different abbreviations for that time. UTC-07:00 is during US DST observance called PDT in the US Pacific Zone and not MST, just because it is the same offset as in Phoenix. Another implication of using AEDT instead of LHHT is, that one may see a clock set to AEDT and cannot derive what if will be after the end of DST, either AEST of LHST. So I now favor keeping LHHT as it is given in the patch. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
