 SCP-224 is a wooden grandfather clock, accented with a black lacquer and gold leaf. Though internal examination of its components has been done, the density and construction of its gears make method of function impossible to interpret. The hands of the clock do not move with any known consistency, though the tendency seems to be generally clockwise. Chimes occur at non-regular intervals, ranging from approximately one minute to several months. To further complicate matters, the numbers on the clock also have a tendency to move and shift, though they generally retain ascending order. Each chime has an anomalous acoustic signature that causes a drastic localized temporal acceleration. People and objects in range of the sound begin to age.
