2.8.9.6 NTP Output Timescale
You can choose the timescale VersaSync will use for the time stamps it sends out to its
NTP clients and network nodes. This is done by setting VersaSync SystemTime times-
cale. The options are UTC, TAI and GPS. Typically, UTC is used for network syn-
chronization.
Note that the System Time affects not only NTP output, but also all other aspects of time
management e.g., time distributed via channels other than NTP, logging, and time dis-
played in the Web UI.
If VersaSync is operated as a Stratum2 server, i.e. as a client to a Stratum1 server (see
"Configuring "NTP Stratum Synchronization"" on page107), the other server will over-
ride VersaSync's System Timescale, should it be different.
Note: IMPORTANT: Make sure you select your desired timescale! Using the
wrong timescale will inevitably result in an undesired time error in your
NTP clients.
To change the system timescale VersaSync will use for its NTP output (and other outputs):
1.
Navigate to MANAGEMENT > OTHER: Time Management:
2.
In the System Time panel, click the GEAR icon.
3.
In the Edit System Time window, select the System Timescale VersaSync will be
in:
UTC: The network PCs will receive UTC time via NTP.
TAI: The network PCs will receive TAI time via NTP.
GPS: The network PCs will receive GPS time via NTP.
