Whether you need to reboot or not depends on your motherboard/BIOS. Some
BIOS, at least when using nvram-wakeup to set the alarm time, need a
reboot before it writes the time to the RTC. If your system wakes up at
the correct time after setting the time using ACPI and then shutting
down then your script needs to return '0' so that mythshutdown knows not
to perform a reboot.

In earlier versions of mythshutdown the format of the time that was
passed to the command to set the time in the BIOS was hardcoded. There's
been quite a few changes to mythshutdown over the last few months to
make it more flexible including a new setting that allows the time
format to be specified.
