Chapter 6 Clock Module Reference Data
Stratum 3E Clock Module
When serving as the master clock, the Stratum 3E Clock module controls the
operation of the Input and Output modules and downloads module configuration
information to all modules, requests measurement data and status from the Input
modules, and sets the Output modules to use currently selected Clock signals. The
Stratum 3E Clock module also contains a battery powered clock that maintains the
clock for timestamping events. The Clock module software reads the clock on
startup and sets the clock when the system time is changed. The timestamp is
referenced as the number of seconds since 00:00:00 January 1, 1980.
