Suprizingly obscure from the oft taught mnemonic of "telling time by the sun on the temple."
Originally written showing the ancient radical for sun next to the ancient radical for stop, possibly having a meaning such as "end of the day" and thus symbolizing the passage of time. However at some point the radical that represented stop became confused and replaced with the radical that represents a growing plant and at a later stage even this was represented with the radical which represents temple.
Temple was probably used photonetically to express move but also lended connotations of regularity. Thus, regular movement of the sun, in effect, time. Hour is an associated meaning.
