Attached are two scripts that I use to set the RTC wakeup time for my
combined FE/BE that may be helpful in writing your script.
MythSetWakeup accepts time_t as input and sets the computer to wake up
at the earlier of the time for the next recording or the next time
mythfilldatabase needs to be run, which for my box is around 3am.  The
second script, MythShutdownWrapper, checks to see if a wakeup alarm is
set, if not, the script sets the box to wakeup at 3am by running the
MythSetWakeup command with "0" as the argument.  I needed
MythShutdownWrapper because the backend will not run the script to
wakeup for the next recording when there is no recording scheduled.

Hope these scripts are helpful,

Rod
