Bug #75790 [NEW]: DateTimeZone::getTransitions(start,end)->ts is incorrect

From: z dot dacto at gmail dot com Operating system: Linux debian 3.16.0-4-amd64 PHP version: 5.6.33 Package: Date/time related Bug Type: Bug Bug description:DateTimeZone::getTransitions(start,end)->ts is incorrect 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 bug report at https://bugs.php.net/bug.php?id=75790&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75790&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75790&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75790&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75790&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75790&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75790&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75790&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75790&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75790&r=support Expected behavior: https://bugs.php.net/fix.php?id=75790&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75790&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75790&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75790&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75790&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75790&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75790&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75790&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75790&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75790&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75790&r=mysqlcfg
