Time Sync operation
Normal Time Synch operation is for the Synchronizer NIM, the lowest-address NIM that has an EPNI
board and the best LCN clock status, to send hardware recognized Time Synch message, followed by a
matching synchtime message containing the exact time of the Time Synch message transmission. This is
done at nominal 6 second intervals.
