Currently one of the worlds oldest timepiece, a sundial sketched onto a flake of limesone was found during this year's excavations in the Vally of the Kings, in an area where workmen lived in the 13th C BCE. On the ostracon a semicircle has been drawn in black ink, subdivided into 12 segments of about 15 degrees, and there's a small dent at the center for a pointer to be inserted. There's even a dot in the middle of each section to mark the half-hours.
