3.1 The Time Management Screen
The Time Management screen is the point of entry for all SystemTime-related settings that are
user-configurable.
To access the Time Management screen:
1.
Navigate to MANAGEMENT > OTHER: Time Management.
2.
The Time Management screen opens. It is divided into 4 panels:
System Time panel
The System Time panel displays the time scale and the year, and allows access to the Edit Sys-
tem Time window via the GEAR icon in the top-right corner. This window is used to select the
time scale, and to manually set a user- time, if so required.
See "System Time" on page148.
Offsets panel
The Timescales UTC, TAI, and the GPS-supplied time are offset by several seconds, e.g. to
accommodate leap seconds. The GPS offset may change over time, and can be managed via
the GEAR icon in the top-right corner of this panel.
Leap Second Info panel
From time to time, a leap second is applied to UTC, in order to adjust UTC to the actual pos-
ition of the sun. Via the Leap Second Info panel, leap second corrections can be applied to
SecureSync’s time keeping. It is also possible to enter the exact day and time when the leap
second is to be applied, and to delete a leap second.
