VelaSync’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.

that have already been created are displayed in the Local Clocks panel.

System Time
The time that VelaSync maintains is referred to as the
System Time
. The System Time is
used to supply time to all of the available time-of-day outputs (such as NTP time stamps,
time stamps in the log entries, ASCII data outputs, etc.).
By default, the System Time is synchronized to VelaSync’s input references (such as
GNSS, IRIG, ASCII data, NTP, PTP, etc.).
If a UTC-based time is not required, however, it is also possible to manually set the System
Time to a desired time/date, or to use the unit's battery backed time (Real Time Clock) as
System Time (with an external 1PPS reference).
The flow chart below illustrates how VelaSync obtains the highest available and valid ref-
erence, depending on whether an external source is chosen as reference, or an internal
(

, or
Local System
).
