2.15 Configuring NTP
Note that the System Time affects not only NTP output, but also all other aspects of time man
agement e.g., time distributed via channels other than NTP, logging, and time displayed on the
unit front panel and in the Web UI.
If SecureSync is operated as a Stratum 2 server, i.e. as a client to a Stratum 1 server (see "Con
figuring "NTP Stratum Synchronization"" on page 98 ), the other server will override
SecureSync's System Timescale, should it be different.

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.
Note: When the Timescale is set to "GPS", the
must be set correctly. As of July 2015, the offset between UTC and
GPS is 17 seconds.
