Note: If Auto is chosen as the format group, the format
will automatically be Auto-detect. VersaSync will
attempt to identify the format of the incoming ASCII mes-
sage.
Offset: Provides the ability to account for ASCII input cable delays or
other latencies in the ASCII input. The Offset value is entered and dis-
played in nanoseconds (ns). The available Offset range is –500 to
+500 ms.
Timescale: Used to select the time base for the incoming ASCII time
code data. The entered Timescale is used by the system to convert
the time in the incoming ASCII data stream to UTC time for use by the
System Time. The available choices are:
UTC: Coordinated Universal Time ("temps universel coor-
donné"), also referred to as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites
(as of 5-March-2024, 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 page156
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 Times-
cale field set to “Local”, select the name of a previously created
Local Clock. See for more information on Local Clocks.
