Edit report at https://bugs.php.net/bug.php?id=76576&edit=1 ID: 76576 Comment by: nospam at tils dot org Reported by: nospam at tils dot org Summary: DateTime formats different Timezones with 'e' and 'T' format codes Status: Open Type: Bug Package: Date/time related Operating System: Ubuntu PHP Version: 7.2.7 Block user comment: N Private report: N New Comment: Regarding your assumption I added the output of DateTime::listAbbrevations(). I didnt find a method to add a file here, so here you can find it: https://cloud.tils.org/index.php/s/9DSZSL8arndXG7b Previous Comments: ------------------------------------------------------------------------ [2018-07-04 09:09:15] requinix@php.net Well, all I can think of is that your timezone database is messed up and somehow has a "UTC" timezone mapped to CEST. ------------------------------------------------------------------------ [2018-07-04 08:59:55] nospam at tils dot org I have one machine: OpenSuSE Tumbleweed with 20180626 php 5.6.31 The other machine is a docker container with Ubuntu 16.04.4 LTS and php 7.2.7 The output of ini_get('date.timezone') on the (working) 5.6 installation is "UTC", on the (broken) 7.2 installation is "". If I add an ini_set('date.timezone', 'UTC') the 7.2 also shows the same problem. I start the very same script inside the docker container by php-cli and outside in the host system. So yes, they are the same. ------------------------------------------------------------------------ [2018-07-04 08:51:03] requinix@php.net I can't figure out how to reproduce this. Are you running that exact script? Unchanged? Are you doing anything else with timezones? Do you have the date.timezone setting something other than UTC? ------------------------------------------------------------------------ [2018-07-04 08:13:16] nospam at tils dot org Description: ------------ If you set a timezone on a DateTime object and you output "e" and "T" values, different Timezones will be returned. I have a german system here and PHP 7.2 seems to always output the system timezone in "T", but output the manually assigned timezone in "e". In PHP 5.6 the output of the test script is: "12:15:03 UTC UTC" In PHP 7.2.7 the output is: "12:15:03 UTC CEST" Test script: --------------- <?php $date = new Datetime('2018-05-01 12:15:03'); $date->setTimeZone(new DateTimeZone('UTC')); echo $date->format('H:i:s e T'); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76576&edit=1
