The sundial was used in the old days to tell the time of day. The sun's movement across the daytime sky would project a shadow onto the surface, (ground), below the stake, (which was stuck in the ground on the earliest versions). The sundial only worked in the daylight hours, (obviously), and I've never heard of a "Moondial" or anything of that nature so I guess they had no means of telling time at night.
