Not necessarily, you can just set you 'mythsettime' script to do the necessary
conversion from localtime to UTC. Mine is like this (there is no doubt an
stella ~ # cat /usr/bin/mythsettime
# $1 is the redundant --settime switch
# Set the hardware clock to system time here, cause it knackers the alarm
# Write the time to myth.time (why - I dunno)
sudo date -d "1970-01-01 $2 sec" +"%F %H:%M:%S" > /home/mythtv/myth.time
# Now convert that to UTC time (cause I want UTC on the mobo and BST/GMT
sudo date -d "1970-01-01 $2 sec" +"%F %H:%M:%S" > /proc/acpi/alarm
Note if you are lucky enough to have a system where setting the h/w clock
knackers the alarm func. you need to configure your ntp stuff to not update
the clock and then rely on the mythsettime script to do it.
Note : I have this hasn't been tested through a summer/winter time change yet
so it could cease to work correctly.
