kolab 3.1 / centos 6.5 - php roundcubemail errors - problem with calender entries disappearing

[hoagie]

Hi,

I have problems with my calender entries.
Whenever I add a calender entry via roundcubemail, it just stays visible
until I click on another page and return to the calender. entries are
always gone.

/var/log/apache/error_log shows the PHP-errors related to timezone settings:

1.) this happens whenever I click a link in roundcubemail (ex. settings,
files, inbox, calender, ...)

------
[error] [client x.x.x.x] PHP Warning:  strtotime(): It is not safe to
rely on the system's timezone settings. You are *required* to use the
date.timezone setting or the date_default_timezone_set() function. In
case you used any of those methods and you are still getting this
warning, you most likely misspelled the timezone identifier. We selected
'Europe/Berlin' for 'CET/1.0/no DST' instead in
/usr/share/roundcubemail/program/lib/Roundcube/rcube_session.php on line
176, referer: https://www.example.com/roundcubemail/?_task=calendar

2.) whenever I create a calender entry, the following error is shown:

------
[error] [client x.x.x.x] PHP Fatal error:  Uncaught exception
'Exception' with message 'DateTime::__construct(): It is not safe to
rely on the system's timezone settings. You are *required* to use the

warning, you most likely misspelled the timezone identifier. We selected

kolab-freebusyd.log also shows:
----------
kolab-freebusyd(2156) KSystemTimeZonesPrivate::readConfig: readConfig():
local zone= "UTC"
kolab-freebusyd(2156) KSystemTimeZonesPrivate::readZoneTab: readZoneTab(
"/usr/share/zoneinfo/zone.tab" )
(23:45:02) commonconversion.cpp(42):    normalized  "Europe/Berlin"
--------------


I can reproduce this error on every calender (Personal, shared Calender)
- the entry always disappears.

Since I do not speak PHP i´d rather not mess around with the file
"/usr/share/roundcubemail/plugins/calendar/drivers/kolab/kolab_calendar.php"

I have verified that my system has the proper /etc/localtime set (i set
it to Europe/Vienna), and i have set the same timezone in /etc/php.ini
(date.timezone=Europa/Vienna)

It might not be related, but I also seem to have a SSL problem, but
authentication seems to work tough:

kolab-freebusyd.log shows:
-----------

but running 'openssl s_client -showcerts -connect localhost:993' shows
correctly my certificate issues for the right FQDN of the server
(www.example.com).


I found this entry in the mailing-list:
http://lists.kolab.org/pipermail/devel/2013-May/014325.html
but since I cannot the php it is not of help for me.

Any ideas what could be wrong?


Tnx.

Hoagie
