Number Pattern Keeps Appearing on the Clock

Question:
The following pattern keeps appearing almost every time I look at my clock. 636-363-484-1001-1221-202-515-333. I know the meaning of 333, but the other constellations are a new phenomenon. Can anybody help? And where can I find the answer? I don't see anything on this site.
