A timer is absolutely essential to have if you are growing plants that need a specific light cycle - the light / dark photoperiods - like flowering plants need. You can program on/off times down to 30 minute increments if so needed. Very accurate and very dependable.
Mechanical timers regulate their speed. Inaccurate, cheap mechanisms use a flat beater that spins against air resistance. More accurate mechanisms have mechanisms similar to mechanical alarm clocks; they require no power, and can be stored for long periods of time. The most widely-known application is to control explosives.
