[time-nuts] Possibly off topic - Jitter on Ethernet over, power adapters

I use a number of power line switches in my home environment. Primarily 
Insteon devices which are similar, but much improved version of the X-10 

For powerline communications, the data bursts are timed with the 
zero-crossing point of the power line signal. This implies that some 
sort of buffering is required to make sure the data is transferred 
during this interval. If your Ethernet device uses same technique, would 
there not be jitter imposed by the relationship of your expected data 
and the required synchronization of the power line signal?
