I run a Horde installation on a openSUSE Tumbleweed. Up to and including
php-7.3.1 time was displayed properly in the calendar application (Kronolith)
that comes with Horde. After the upgrade to php-7.3.2, existing events are
shown with a 2 hour offset. After some experimentation I have come to the
conclusion that this is caused by an openSUSE modification with the
'php7-systzdata-v17.patch'. With the patch applied the displayed time is wrong,
without it the time is correct.

Possibly related, with the patch applied I see frequent segfaults (several
times per hour) in php-fpm like the following:

[21-Feb-2019 23:02:04] WARNING: [pool www] child 33612 exited on signal 11
(SIGSEGV) after 4218.979829 seconds from start

This is with timezone (in php.ini) set to 'Europe/Amsterdam' with a load of
just a handful of users. Without the patch, no segfaults, which leads me to
believe there might be a relation. There were no problems with php-7.3.1 (time
was displayed correctly and no segfaults).
