Have Quick In/Out - Spectracom SecureSync User Reference Manual

5.4 Time Code Option Cards
The incoming input time information may be provided as local time, but System Time may be con-
figured 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 "Setting up a
Local Clock" on page 175 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.
