Wrong Olson Timezone Offsets?
I'll take your first example here:
[60] => Array ( [ts] => 1236481200 [time] => 2009-03-08T03:00:00+0000 [offset] => -14400 [isdst] => [abbr] => WART )
However, if you check Time&Date the standard offset should be -10800 (3 hours) and not -14400
From what I've read, this is not true; according to this article, around that time (March 3rd 2009) the timezone was changed to UTC-4 when there's no daylight saving and UTC-3 if there is. Though, the mentioned date in the article is March 14/15 and not March 8 ... I'm not sure what has caused that difference.
