 SCP-224 is a wooden grandfather clock, markings remotely observed, date its origin at the end of the 19th century. Though internal examination of its components has been done, the density and construction of its gears make method of function impossible to interpret. Chimes occur at non-regular intervals, ranging from approximately one minute to several months. 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. The amount of time is not consistent with the chimes, ranging from essentially inconsequential amounts to several years. Though the amount aged during any single event is consistent for all objects within the field of effect.
