Description:
------------
The following test script used to work just fine in PHP 7.3.1. Only after the upgrade to php 7.3.2 did I start getting this issue.

Possibly other date functions are affected. But my unit tests stop immediately on failure. Also I haven't changed anything to my environment in months/years. It very much seems to me like a new 7.3.2 issue, and I couldn't see anything in the 7.3.2 log about backwards incompatible changes.

php --version
PHP 7.3.2-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Feb  7 2019 18:01:56) ( NTS )

Test script:
---------------
php -a
Interactive mode enabled

php > var_dump(ini_get('date.timezone'));
php shell code:1:
string(16) "America/New_York"
php > echo strftime('%F %T %z');
2019-02-07 22:24:27 +0000
php > echo strftime('%Z');
GMT

Expected result:
----------------
php > echo strftime('%F<br />%T %Z');
2019-02-07<br />17:04:54 EST


Actual result:
--------------
Always seems to be GMT

Works like expected on <https://3v4l.org/TdMW6>.

Which part of php -i would be relevant?

Is it possibly related to my PHP ppa (ondrej)?

Some more details:

php > echo ini_get('date.timezone');
America/New_York
php > echo date_default_timezone_get();
America/New_York
php > echo strftime('%F %T %z %Z');
2019-02-08 01:19:00 +0000 GMT

php > echo phpinfo();
....

I reverted to 7.3.1, no problem. Upgrade to 7.3.2, problem starts again.

We're seeing the same issue on 7.3.2 and in process of downgrading to 7.3.1
Ubuntu 18.04.1
 [2019-02-08 03:27 UTC] jflambert at newtrax dot com 
Matt, thanks for confirming! Where does your PHP come form? Ondrej PPA? Or built from source?
 [2019-02-08 04:26 UTC] matt at hatchet dot com dot au 
Ondrej PPA too. We ended up popping in Ubuntu disco repo temporarily, downgrading, holding the packages, then removing the disco src. Now having issues with intl but that's probably due to a package it relies on being upgraded. I was able to reproduce the issue on two separate Ubuntu 18.04 boxes using Ondrej PPA

Also working for me. I'm inclined to think the problem is on the PPA side...
 [2019-02-08 05:42 UTC] matt at hatchet dot com dot au 
I've just built from git src and cannot reproduce the issue anymore on 7.3.2 so it appears it may very well be the PPA.

I'm experiencing the same issue since I upgraded to PHP 7.3.2 a few hours ago. I reproduced this on multiple servers and I'm using Debian 9 with the Sury PPA (https://packages.sury.org/php/)...

I hope that there will be a fix for this issue soon.

Similar issue here with PHP 7.3.2-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Feb  7 2019 18:01:56) ( NTS )

strtotime('2013/06/21 12:00:00 Europe/Berlin') returns the same value no matter what timezone name I use.

It was a problem in the PPA after all. Ondrej just fixed it. Everyone should be able to update to the latest deb packages (7.3.2-3+ubuntu18.04.1+deb.sury.org+1)

Next time I'll make sure to run tests via 3v4l.org first!

Kudos to Remi as I used his fixed version of systzdata patch to fix the issue after I botched to update the patch myself.

Hello,

what was the problem? We have the similar issue under opensuse.
