Groupdav broken in 1.8

[Laurent_Leonard]

Hi,

I just installed eGroupware 1.8 (fresh install) and I got the following error
message when I tried to fetch data by groupdav with Kontact:

An error happened
DateTimeZone::__construct() [datetimezone.–construct]: Unknown or bad
timezone ()

Push data by groupdav with Kontact works fine.

I set up timezone in “Common preferences” but it doesn’t fix the issue, any
idea what’s wrong ?

Thank you,

Laurent Léonard

The issue only affects the calendar at fetch time. Same problem if I try to
download an ICS file from a web browser.

The following patch fixes the issue (at least for now, since I don’t need time
zones for my own use):

Please post the trace of the exception from Apache error-log.

Curiously I didn’t found any related message in Apache error log, I only have
that message that appears in the authentication window… But my last message
should help you to find the cause of the issue. The $tzid variable is always an
empty string (displayed in parentheses in the error message) and set it with a
valid string fixes the issue.

Thank you,

Then you either not looking in the right error-log, or logging of php
errors is switched of in your php.ini.

should help you to find the cause of the issue. The $tzid variable is always an
empty string (displayed in parentheses in the error message) and set it with a
valid string fixes the issue.

That’s not a fix, it simply switched all timezone processing of in favor
of one hard-coded timezone.

A fix could be to set the user timezone, if and only if timezone
parameter is empty.

Thought that still does NOT explain, why and from where the timezone
class got called with an empty timezone. To solve that, we need the
trace from Apache error-log from you.

Here is what I get in error log:

  calendar_ical::exportVCal() unknown TZID=‘System/Localtime’, defaulting to
  user timezone ‘Europe/Brussels’!

• when the user time zone is not set:
  calendar_ical::exportVCal() unknown TZID=‘System/Localtime’, defaulting to
  user timezone ‘System/Localtime’!

‘System/Localtime’ is NOT a valid timezone, you need to replace it in
your php.ini with a correct one like eg. ‘Europe/Brussels’.

I know that’s the default in Debian/Ubuntu, but we can NOT retrieve the
timezone rules for iCal export, from ‘System/Localtime’.

‘System/Localtime’ is NOT a valid timezone, you need to replace it in
your php.ini with a correct one like eg. ‘Europe/Brussels’.

I tried to override date.timezone with an Apache directive:
php_value date.timezone Europe/Paris

I also tried to change it in php.ini, but it didn’t change anything…

I know that’s the default in Debian/Ubuntu, but we can NOT retrieve the
timezone rules for iCal export, from ‘System/Localtime’.

On Debian GNU/Linux, there is no default time zone in php.ini.
“date.timezone =” is commented out.

Thank you,

Laurent Léonard

On Debian GNU/Linux, there is no default time zone in php.ini.
“date.timezone =” is commented out.

I finally solved the problem.

First of all, timezone should be set in common preferences (default or per
user value). If events were created before that operation (with an invalid
tomezone like “System/Localtime” it will generate the error even if the
timezone is set. In that case events with an invalid timezone should be fixed
too.

Secondly, “date.timezone” should be set in the php.ini file. Setting
"date.timezone" by a php_value directive in the EGroupware Apache configuration
file doesn’t work because the cron task script reads the value from the php.ini
file and set the configuration entry “server_timezone” in database ("egw_config"
table). On Debian GNU/Linux (and Ubuntu probably) the cron task will generate
the following cron message if it is not set:
“egw::setup() stored server_timezone=System/Localtime”

Debian like systems are widely used, so it should be great if that piece of
information could be posted on a wiki or a documentation file.

Hi Laurent,

I added it - in brief form - to the 1.8 release notes:

www.egroupware.org/wiki/releasenotes1.8

Not sure they get read, but that’s a different story …

If no timezone is set in user or default preferences, we are defaulting
to server timezone.

The updated release candidate has now an installation check, making sure
date.timezone is set (and NOT System/Localtime).
