Marking it as a "Documentation Problem". Previous Comments: ------------------------------------------------------------------------ [2018-01-10 08:15:34] z dot dacto at gmail dot com Description: ------------ When optional argument $timestamp_begin is provided to DateTimeZone::getTransitions the first transition returned assumes a ts value of $timestamp_begin and a time value formatted from $timestamp_begin. The first transition should instead be the one active during $timestamp_begin. Test script: --------------- <!DOCTYPE html> <html> <body> <pre> <?php $tz = new DateTimeZone('America/Los_Angeles'); # 1509872300 = 11-05-2017T8:58:20+0000 # 1515570270 = 01-10-2018T7:44:30+0000 $transition = $tz->getTransitions(1509872300, 1515570270); print_r($transition); ?> </pre> </body> </html> Expected result: ---------------- Array ( [0] => Array ( [ts] => 1489312800 [time] => 2017-03-12T10:00:00+0000 [offset] => -25200 [isdst] => 1 [abbr] => PDT ) [1] => Array ( [ts] => 1509872400 [time] => 2017-11-05T09:00:00+0000 [offset] => -28800 [isdst] => [abbr] => PST ) ) Actual result: -------------- Array ( [0] => Array ( [ts] => 1509872300 [time] => 2017-11-05T08:58:20+0000 [offset] => -25200 [isdst] => 1 [abbr] => PDT ) [1] => Array ( [ts] => 1509872400 [time] => 2017-11-05T09:00:00+0000 [offset] => -28800 [isdst] => [abbr] => PST ) ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75790&edit=1
