I think the research is more about understanding the frequency and time 
shifts across the network, referred to a more accurate and stable 
reference.  Not so much trying to use the grid as a time/frequency 
reference.

For instance, is the variation in phase across the San Fernando Valley 
different in the afternoon when everyone turns on their air conditioner 
- sure there's a "voltage at the user" change, but is there also a phase 
change.
