Overtime is formed from "over-" (meaning beyond or excessive) and "time" (from Old English "tima", meaning a period or duration). The word refers to time worked beyond the regular hours, hence excessive time spent working.
Think of 'over' meaning beyond, and 'time' as a period — overtime means working beyond the usual time.
