Timescale: Used to select the time base for the incoming time code data. The
entered Timescale is used by the system to convert the time in the incoming data
stream to UTC time for use by the System Time. The available choices are:
UTC: Coordinated Universal Time ("temps universel coordonné"), also
referred to as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as of 15-Febru-
ary-2021, this is 18 seconds ahead of UTC time)
A local clock set up through the Time Management Page: This option will
appear under the name of the local clock you have set up. Refer to "The Time
Management Screen" on page166 for more information on how to configure
and read the System Time. Local timescale allows a Local Clock to apply a
time offset for Time Zone and DST correction.
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 laten-
cies in the HAVE QUICK outputs. The Offset values are entered in nanoseconds
(ns). The available Offset range is –500 to +500ms.
