If it needs --force every time then your system time is drifting more tha=
n
1800 secs (30 mins) between settings, which means something is seriously
wrong.

One thing is that your clock might not be getting set right on
shutdown/startup. The mechanism for saving the system clock into the
hardware clock correctly (so that the hardware clock correctly sets the
system clock) varies per distro, but it is pretty important to get it
right.

On a system that runs solely on linux (and I'm guessing no one is running
mythtv dual boot with windows) it is easiest to set the hardware clock to
UTC (GMT). The system clock runs on UTC anyway, and the translation to
your local timezone is done via /etc/localtime, or the TZ environment
variable.

But anyway, enough detail, if you need --force each time you update,
something is wrong!
