It now | commences from the last Sunday in September, when 2.00am becomes 3.00am, | and ends on the first Sunday in April the following year, when 3.00am | becomes 2.00am. That is correct. | Instead into the Australasia table : | | Rule NZ 2008 max - Apr Sun>=1 2:00s 0 S | | instead of 3:00 ... Not instead of, but "another way of writing". When the above text says .. "when 3.00am becomes 2.00am" it obviously means that 03:00 summer time turns into 02:00 standard time (which is correct). In the TZ data, the authors of that rule chose to use "2:00s" - the "s" indicates standard time, instead of wallclock time. That is, Summer Time ends at 02:00 standard time (which is correct, and also was, very briefly, 03:00 Summer time, just before the change back). | so can please someone told me at what time is supposed to start the April | DST on New Zealand? It is what both of the above say, 02:00 standard time, or 03:00 wallclock time - but of course, that's when summer time ends, not when it starts (Australia and NZ are in the Southern Hemisphere after all, it is summer in January, not July...) kre
