Spectracom SecureSync User Manual

The incoming input time information may be provided as local time, but System Time may be
configured as UTC time, so internal computations need to be performed. With the Timescale
field set to “Local”, select the name of a previously created Local Clock. The Time Zone and DST
rules, as configured in the Local Clock will be applied to the front panel time display. Refer to
for more information on Local Clocks.
Offset: Provides the ability to account for HAVE QUICK cable delays or other latencies
in the HAVE QUICK outputs. The Offset values are entered in nanoseconds (ns). The avail-
able Offset range is –500 to +500 ms.
