Exactly how the XO-1 mesh functions on this level is frustratingly
unknown, but when I did a couple of simple observations once before,
the clocks appear to synchronize with the neighbours.

I mean the clock in the 802.11 MAC sublayer. This defines the basis of
the timing synchronization function (TSF) which is a core part of
802.11. Without synchronized clocks, nodes cannot communicate.
