Daylight Saving Time commences on Sunday 30th September 2012 and | ends on Sunday 7th of April 2013. Thanks for the update. | Please find link below for more information. | http://www.mcil.gov.ws/mcil_publications.html I note that that also includes Summer Time dates for the summer of 2013/4 which look as if they may be following the pattern of summer time (daylight savings) running from the last Sunday in September to the first Sunday in April - so I am going to assume that for years even further into the future in the patch I am submitting below for consideration. If you have any reason to believe a different rule is likely to apply, now, or any time in the future (and/or if there are any exception years) we'd appreciate learning of it as far in advance of the change as possible (3 weeks notice is not really enough preparation time for most users of this data). kre The following patch is against the (as yet unannounced) tzdata2012f release. --- australasia 2012-08-31 20:27:35.000000000 +0700 +++ australasia.new 2012-09-13 16:03:52.000000000 +0700 @@ -628,6 +628,25 @@ # Although Samoa has used Daylight Saving Time in the 2010-2011 and 2011-2012 # seasons, there is not yet any indication that this trend will continue on # a regular basis.
