HDMI Scheduled On/Off

The below comamnds will setup automatic on/off of the monitor connected to the HDMI port on your PiFrame. This is handy as overnight few people are looking at their photos and by turning off the display you'll save power and make the screen last longer.

The below is setup to turn the display on at 0600 and off at 0000. Please adjust accordingly.
