Observer Matrix : Matrix CLI : Matrix CLI : system general time source
   
system general time source
The system general time source command defines how system time is set on the Matrix.
 
Usage
system general time source <TimeSource>
 
 
Parameters
Parameter
Description
TimeSource
Clock source establishes the system time and is used for packet timestamping.
 
NONE No configuration is necessary, but any system's time is highly vulnerable to clock drift unless it uses an outside time synchronization source.
IEEE-1588 IEEE-1588 is the Precision Time Protocol (PTP) specification. An IEEE 1588-2008 server with an accurate time source can provide higher resolution and accuracy than NTP. The IEEE 1588-2008 master time server must be accessible on the same network subnet as the monitor port.
GPS Uses an external GPS connected to the GPS port on the rear of the device. Only GPS Time Synchronization System appliances sold by VIAVI may be used. The GPS Time Synchronization System can provide the highest resolution and accuracy.
NTP Synchronizing with Network Time Protocol servers or pools can provide a low resolution, accurate time source. If NTP is chosen, one or more NTP servers or pools must be defined.
