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 July,
2015, this is 17 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 Sys-
tem 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. See .
Note: The Timescale of the ASCII input (as configured in the ASCII
time source) must be set correctly, especially if other input ref-
erences are enabled.
Failure to configure the Timescale of the ASCII input correctly could
result in time jumps occurring in the System Time when input ref-
erence changes occur. These time jumps could affect NTP and nor-
mal operation of the system.
Baud Rate: Determines the speed that the output port will operate at.
Data Bits: Defines the number of data bits for the output port.
Parity: Configures the parity checking of the output port.
Stop Bits: Defines the number of stop bits for the output.
