Other VelaSync outputs will be provided in the same timescale that is selected in the Sys-
tem timescale field. The NTP output for network synchronization and the time stamps
included in all log entries will be in the same timescale as the configured System timescale.
For example, if “GPS” is selected as the System timescale, the log entries and the time dis-
tributed to the network will all be in GPS time (time broadcasted directly from the GNSS
constellation).
3.2.1.3 Manually Setting the Time
For some applications, it may not be necessary to synchronize VelaSync to a UTC-based
reference. Or, a GPS reference is not available yet (e.g., because the antenna is not yet
installed), but the system has to be setup and tested.
In such cases, the System Time can be hand-set, and then used as a User [x] -set System
Time. For more information on when to use this functionality, see "The "User/User" Refer-
ence" on page 116 .
Note: If synchronization to UTC is NOT required, it is advisable to set a time
in the past or future, so as to avoid users inadvertently considering the dis-
tributed time to be genuine.
Caution: Note that this mode of operation is intended for special use cases
e.g., autonomous systems, where legally traceable time is not required:
This time will be inaccurate/not traceable, since it is not tied to any ref-
erence.
To hand-set the System Time, and configure this time to be a valid reference:
1. Navigate to MANAGEMENT > OTHER: Time Management .
2.
In the System Time panel on the left, click the GEAR icon.
3.
Select Manual Time Set . Set your time & date, as needed:
System Time [DATE; TIME]: If you do not select Set Year Only , this box will
show the current time in the format:
Year-Month-Day Hour:Minute:Se-
cond
. To set the time manually, click anywhere in the System Time field. A
drop-down calendar with time-setting sliders will appear:
