APPENDIX
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 per-
formed. 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. See also .

Format: Used to configure the formatting of the four available HAVE
QUICK outputs. The available output formats are as follows:
STANAG 4246 HQ I
STANAG 4246 HQ II
STANAG 4372 HQ IIA
STANAG 4430 Ext HQ (Extended HAVE QUICK)
STANAG 4430 STM (Standard Time Message)
ICD-GPS-060A BCD
ICD-GPS-060A HQ
DOD-STD-1399 BCD
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 avail-
able 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
22-August-2023, 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 page 186
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 cor-
rection.
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 available Offset range is –500 to +500 ms.
