Consider a lighting contactor. I've used them in commercial and residential projects for security lighting and/or landscape lighting projects. A single time clock can be used to power up multiple circuits or lighting loads at the same time. I recently used a 16 pole contactor for a large residential project to control low voltage, line voltage, and motor loads (water pumps for fountains). I used 13 poles of a 16 pole contactor so there is room for expansion. I'm controlling it with an Intermatic astronomical time clock for self-adjusting dusk to dawn & daylight savings time operation.
As an electrician, here's what I see so far. You've got a double-pole 30amp breaker feeding a 20a 250volt receptacle with an unknown wire size gauge connecting them. Regardless, it's not simple or cost effective to split this into 2 circuits. You've got 2 hots and a ground wire going to the receptacle and will need 2 hots, 2 neutrals (or 1 shared neutral) and a ground wire for the 2 circuits. This means you're already short a wire right off the start unless you combine your grounds and neutrals (not recommended even though they are technically tied together within the circuit panel box).

As an electrician, I will offer up a little information in hopes of helping clarify things. First and foremost, controllers should always use grounded plugs into GFCI receptacles or circuits protected by GFCI breakers. After that, it becomes your choice as to how strictly you wish to adhere to the NEC (National Electrical Code). The NEC is written primarily in the interest of safety and satisfaction of requirements for insurance purposes. As soon as you elect to use a product outside of it's rated use (ie: SPT outdoors) a code violation occurs and you have, in essence, given your insuran
