provided in the same timescale. For example, the System timescale can be configured as "UTC",
but the front panel LED display can be configured to still show "local" time, if desired.
Other SecureSync outputs will be provided in the same timescale that is selected in the System
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 distributed to the network
will all be in GPS time (time broadcasted directly from the GNSS constellation). But, the LED dis-
play can still be configured to show the current "local" time.
In most cases, "UTC" will be the desired Timescale to select.
