Description: SCP XXXX is a wooden clock. Its face has a diameter of 10cm and has 3 hands. It is unknown how it is powered. The anomalous feature of this clock is that it always keeps perfect time, no matter which time zone it enters it will always read accurately to the millisecond. The clock seems to have no method of changing the hands. We have yet to reverse engineer this SCP.
