Hard to know what you are meaning?
A timer is a device in a circuit that switches on then off at given times. There may be many on/off operations not just the one.
Think of some lights, say street lights that come on at a certain time then off at a later time. If they are electric that would fit you question.
Although the lights are more likely controlled by darkness at dusk and first light in a morning.

What would happened if you wired a 240v ballast and a 120 v ballast into a heavy duty timer?
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
