applied to 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.

You can create multiple different Local Clocks, as needed. The names of all Local Clocks
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 Sys-
tem 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
(
User[x]
, or
Local System
).
