Opinion on timing system for synchrotron beamlines

[Márcio Paduan Donadio <marcio.donadio@lnls.br>]

     I'd like to know your experience regarding integration of the 
accelerator timing system with the beamlines:
     - Which accelerator events are useful for the beamlines' control 
system.
     - Do the beamlines use a global and very precise timestamp sent 
from the accelerator timing system? What is the time precision?
     - Do you think that a PTP system is sufficient for timestamping 
experiments in beamlines?
     - What is the EPICS role regarding such a timing system?

     Thank you,
