Note: In newer versions of KnoppMyth (e.g. R5F1) you need to use a different command to set the system timezone. Either

/usr/local/bin/KnoppMyth-tz

or

dpkg-reconfigure tzdata

If you have a problem after you have your timezone correct and the system time correct then check the xmltv time offset. Go into mythtv setup. Go into the general section. Once there go to the third page. You will see an option that says Time offset for xmltv listings. Set this to auto. If it is set to none it assumes any xmltv guide data is local and might have your shows coming on the utc schedule. Auto will take your timezone into account and change the shows appropriately.

For older versions, this is typically the result of having started the various backend servers and run mythfilldatabase before the clock and/or timezone was set correctly. The thing that trips up a lot of people is that you need to restart the servers after the timezone has been fixed for it to fully take effect. Because the program information saved in the DB is normalized using the current time setting at the time it was loaded, you also need to purge that and reload it. The directions below take you through all the necessary steps.

• Your system time should be set to local time. Use tzconfig or webmin and set your timezone and time correctly for your location. Use hwclock --systohc or webmin to push the setting from the system clock into the BIOS hardware clock. See the LinuxTips page for more on how to run these commands. Note that after following these directions the BIOS time will be set to UTC since that is how the system stores the time internally.

• Reboot and make sure that your time settings stuck.

• Run mythtv-setup either following the GettingBackIntoMytTVsetup directions or the ones below, and under "Video Sources" select the option to delete your program guide data. Recreate your video sources, make sure that your "Input Connections" are set up correctly, then exit and run mythfilldatabase as the mythtv user.

The following is one way of doing this entirely from the command line. As root:

man tzconfig
man hwclock
tzconfig
hwclock --systohc
reboot

After reboot as root again:

/etc/init.d/mythtv-backend stop
mythtv-setup
/etc/init.d/mythtv-backend start
su - mythtv /usr/bin/mythfilldatabase

Running mythtv-setup over again sucks. I recommend trying

mythfilldatabase --refresh-all 

in place of mythtv-setup (if it doesn't work you're no worse off, you can still run mythtv-setup as a last resort). Don't run mythfilldatabase with --refresh-all unless you really NEED to - it puts greater strain on program data servers!
