[Bug 1027871] [NEW] EIT not observing timezone correctly

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Found that program information from EIT time offset is wrong after
upgrade to 0.26, and it breaks the custom rules that use
program.starttime comparisons.  For me, in NZ, the timezone is
Pacific/Auckland which is NZST officially (UTC+1200), however the
program table shows entries for 6pm occuring at 0600.

Interestingly, when frontend displays the program guide, the correct
AM/PM indications is given.  So, it must just be a hook to custom
recording schedules that is broken.  Some information below:

$ cat /etc/timezone
Pacific/Auckland

$ date
Mon Jul 23 22:30:41 NZST 2012

$ date -R
Mon, 23 Jul 2012 22:30:44 +1200

The following recording rule, is an example that currently finds NOTHING
to record.  It should match 'ONE News At 6pm', daily.


INSERT INTO `record` VALUES (556,9,0,'10:46:23','2012-06-17','10:46:23','2012-06-17','TV ONE News (Power Search)','','program.title LIKE \'%news%\' AND HOUR(program.starttime) >= 18 AND HOUR(program.starttime) < 21 AND (channel.callsign = \'TV ONE\')',0,0,'','Default',0,1,3,1,0,0,'Default',1,15,'','','','',1,0,0,0,0,0,0,0,1,'00:00:00',735036,0,0,0,'Default',0,'0000-00-00 00:00:00','2012-07-21 18:37:14','2012-07-22 06:22:31','Default',9,0)

I have tried changing both "TimeOffset" and "EITTimeOffset" values in
the settings table to reflect our TZ (+1200), but hasn't helped.

mysql> select * from settings where value like '%offset%';
+---------------------+------+-----------+
