I believe that the parenthetical reference to New Zealand time being +12/+13 was only intended to point out what time it is there. The reference to Samoa being one hour ahead is a generalization, but it may be one that's unintentionally too broad.
I'm new, so please ignore this if it's garbage.The most recent comment in the australasia file on Samoa from Laupue Raymond Hughes (2011-09-02) gives a link to a Samoan goverment website (http://www.mcil.gov.ws/mcil_publications.html) and gives the dates of DST switches for September 2011 and April 2012.The actual database is correct for April 2012 but gives no future rule.According to the website " Samoa will be one hour ahead of NZ (+12Hrs, in Daylight Saving +13Hrs) " this is consistent with the 2012 date given on the website:
Year End Time Start Time 2011 - - - - - - 24 September 3:00am to 4:00am 2012 01 April 4:00am to 3:00am - - - - - - (it's wrong for the 2011 date by one day, but that might be because of the weird one day jump at the end of 2011???)I suggest the rule for the future is updated to be similar to New Zealand but changing one hour later. Something like:Rule WS 2012 max - Sep lastSun 3:00s 1:00 DRule WS 2012 max - Apr Sun>=1 3:00s 0 SPlease excuse me if my syntax is wrong.Samuel--
