Egroupware and KOrganizer time shifts

ingoratsdorf 2013-04-18 01:41:19 UTC #1

Hi,

beeing in a GMT+13 timezone, I seem to be getting all those timezone
bugs accross all products…

This bug happened in the past but was resolved. Either from egw or KDE.

Now it’s back.

When New Zealand was still on summer time, every event I created in
KOrganizer was shifted by 1.5 hours. (later).
Then we switched to winter time and now all events are offset by 0.5
hours. (later).

I noticed that KOrganizer (or the iCal subsytem) is generating a massive
amount of VTIMEZONE information that is sent to egw with the VEVENT PUT
request. the egw Horde subsystem seems to be failing to parse this
VTIMEZONE information:

Looking at the supplied VTIMEZONE information, it seems to be correct,
apart from the unnecessary historic data.

What I was also getting a lot is

[Tue Apr 16 23:31:17 2013] [error] [client 222.154.116.150] PHP

on line 60

To me this is showing that Horde has issues parsing the VTIMEZONE
information and only using the first bit when the time shift was half an
hour and not a full hours (back in 1927).
Now I understand that egw is using it’s own timezone database, and that
this information actually may not be used.

I “fixed” the error by adding the following line into
phpgwapi/inc/class.groupdav.inc.php, line 1309, function PUT(&$options):
$options[‘content’] = preg_replace("/BEGIN:VTIMEZONE.*END:VTIMEZONE/s",
"", $options[‘content’]);

This effectively deletes all timezone information from the submitted
VEVENT data and there is no need to parse t any more.
And voila the errors all disappear and all clients (iphone, lightning,
ical, korganizer) seem to be happy and still working. Time shifts gone.

Question is: When egw is not using the submitted timezone information,
why making an attempt to parse it and maybe fail?

Any thoughts?

Ping.
I still have my patch in there and it is working fine. Without it,
KOrganiser events are still all offset.
So my question remains:

Hi,

I can confirm this issue is still relevant.
It is actually a bug in the Horde framework (that egw is using) that is
parsing timezone information and is expecting an array as result (ie at
least two parameters), however, KDE is supplying historic timezone
information that Horde cannot parse and the parsing function returns a
single parameter that PHP returns not as an Array.
By forcing the return parameter into an array, the bug is gone and all
works.

I can supply more information and patch if useful.

Regards,
Ingo

Hi Ingo,

sorry that it took me so long to come back to your issue.

Can you send me a single event with KDE send VTIMEZONE.

I will have a look and fix it.

Btw. your reasoning is correct, EGroupware does not use any timezone
information contained in VTIMEZONE. We solely rely on PHP’s timezone
handling, which cant be feed with timezone information.

And the following is my patch:
Horde vtimezone cannot handle single RDATE’s and returns a single parameter from getAttribute(‘RDATE’), but not an array, what is expected and the parsing function fails.

phpgwapi/inc/horde/Horde/iCalendar/vtimezone.php
Starting from line 58:

   $rdates = $child->getAttribute('RDATE');
    if (!is_a($rdates, 'PEAR_Error')) {

            // added by IR Ingo Ratsdorf
            if (!is_array($rdates)) $rdates = (array) $rdates;

            foreach ($rdates as $rdate) {
                    $switch_time = $switch_time['value'];
                    $switch_year = date("Y", $switch_time);
                    if ($switch_year == $year) {
                            $t = getdate($switch_time);
                            $result['time'] = @gmmktime($t['hours'], $t['minutes'], $t['seconds'],
                                    $t['mon'], $t['mday'], $t['year']);
                            return $result;
                    }
            }
    }

Cheers,
Ingo
