Starting with MythTV version 0.26, the time zone tables must be loaded in MySQL.
Distributions that don't have the time zone tables loaded:
Ubuntu 12.04 Mythbuntu 12.04 Mythbuntu 10.04 Fedora 16 Fedora 17
Distributions that do have the timezone tables loaded:
Gentoo (confirmed for dev-db/mysql-5.1.61)
To see if the tables are already loaded, enter mysql and type:
SELECT CONVERT_TZ('2012-06-07 12:00:00', 'GMT', 'America/New_York');
If the response looks like:
+--------------------------------------------------------------+
| CONVERT_TZ('2012-06-07 12:00:00', 'GMT', 'America/New_York') |
+--------------------------------------------------------------+
| 2012-06-07 08:00:00 |
+--------------------------------------------------------------+
the tables are loaded and no further action is required.
Note: If the time zone tables are updated, then the
procedure below should be repeated.
If the response looks like:
+--------------------------------------------------------------+
| CONVERT_TZ('2012-06-07 12:00:00', 'GMT', 'America/New_York') |
+--------------------------------------------------------------+
| NULL |
+--------------------------------------------------------------+
then the tables must be loaded.
Assuming the distribution's time zone information is in /usr/share/zoneinfo, type:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p<yourpassword> mysql
Remove the -p<yourpassword> from the above if you don't have one.
Restart MySQL, and repeat the initial test.
