Either it happened and it had to travel along the path of its effect, or it did whatever caused this and the effect rippled outward from it and it stayed at the epicenter. So if your call is the latter, then yeah. Oldest.

If it stayed in the center, the clocks will match along a circle. If it moved, the path will wind. We could either trace it or split up.
