There are a few time zones, all in australia, that seem to use the same designation of the time zone for both daylight and standard time. Is this correct, or is it a bug? # New South Wales # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule AN 1971 1985 - Oct lastSun 2:00s 1:00 - Rule AN 1972 only - Feb 27 2:00s 0 - Rule AN 1973 1981 - Mar Sun>=1 2:00s 0 - Rule AN 1982 only - Apr Sun>=1 2:00s 0 - Rule AN 1983 1985 - Mar Sun>=1 2:00s 0 - Rule AN 1986 1989 - Mar Sun>=15 2:00s 0 - Rule AN 1986 only - Oct 19 2:00s 1:00 - Rule AN 1987 max - Oct lastSun 2:00s 1:00 - Rule AN 1990 1995 - Mar Sun>=1 2:00s 0 - Rule AN 1996 max - Mar lastSun 2:00s 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Australia/Sydney 10:04:52 - LMT 1895 Feb 10:00 - EST 1917 Jan 1 0:01 10:00 Aus EST 1971 Oct 31 2:00s 10:00 AN EST I should also point out that my previous mail was not meant to contain a complete list bad formats. I am only looking at the current year data and also I am deleting the redundant time zones (those that only differ in prior year data) before I was checking for problems. Thanks for your help kenny
