At present, there is no support in the SC BIOS for timer-based power on. You can request this feature if you wish. To do so, directly contact Intel Customer Support and opening a ticket. Here are links for contact information, by geography:
You can also try using the Intel Customer Support Chat Service, but hours are limited to PST TZ.
As for Timer-based system shutdown, this is easily accomplished using standard features in Windows.
Hope this helps,
