Have you had a look at MythWelcome it may already do what you want?

MythWelcome has a daily wakeup/shutdown feature where you can define up 
to 2 periods in the day where you would like your myth system to be 
awake even if it is idle. You would have to let nvram-wakeup set the 
next wakeup time in the BIOS for you. Once you have everything setup 
your system would both wake up to record something or wake up between 
5pm and 1am automatically. One gotcha at the moment is the daily wakeup 
periods cannot cross midnight so you would have to have one period for 
5pm to midnight and an other from midnight to 1am to achieve what you want.
