Is this battery operated or AC powered?
One avenue would be to use a small irrigation timer, they have real time clocks and 12v ac outputs which a bridge could be attached to , one output could be used for a reversing relay .
(p.s. I recall now they could be 24vac.)

Per Max an irrigation timer with a RTC (Real Time Clock) or a small PLC (Programmable Logic Controller) with a RTC. Entire packages can be bought for less than I could ever build one for.

any idea where i can buy these
No, since I haven't a clue as to your location? I would start with a Google of:
irrigation timer with real time clock
Programmable Logic Controller with real time clock
and also...
Smart Relay with real time clock

You may have to work from the digital outputs and configure a few relays to FWD and REV your motor. You also need to consider your motor's current draw in selecting additional components.

Is there just one selection / wk. or multiple selections ? How often do they change ?
How fine are the min. 1 min., 5 min., 15 min. ?
Is the 2 hr. on time fixed for all selected times ?
