Commands
Edit Date
This command changes the system date and time. The command format is:
ED-DAT:[<tid>]::<ctag>::<date>,[<time>]:[MODE=a];
The date/time stamp behavior is as follows:
 During warm-up:
– The date/time displayed starts from 1970 and increments from there. If the
ED-DAT command is used to set the time in local mode, the time is
changed as specified in the command.
 After warm-up:
– If the ED-DAT command has not been used to set the local mode time,
then UTC date and time are displayed.
Parameter Value Description
date in the format
a-b-c
a = <year> 4-digit year
b = 01 to 12 Month
c = 01 to 31 Day
time in the format
a-b-c
a
Note:
a
The <time> value can only be entered when MODE=LOCAL, or in the same com-
mand as MODE=LOCAL, otherwise the command is denied. A successful command
with <time> changes the display of time to conform to the nearest 30 minutes, relative
to UTC.
For example, when the UTC time is 01:12:10, setting the local time to 18:50:30 will
actually set the clock to 18:42:10, because 18:42:10 is the closest 30 minute jump,
relative to UTC, from 18:50:30. This is done to accommodate 30-minute time zones
and still keep the local time accurate to UTC.
a = 00 to 23 Hour of the day
b = 00 to 59 Minutes
c = 00 to 59 Seconds
Mode = a
a = UTC
b
b
If a command includes MODE=UTC, and the GPS signal is not present, the com-
mand is denied.
Uses Universal Coordinated Time from GPS
(cannot be set by TL1 command)
a = LOCAL Uses local time for hours, UTC for minutes and
seconds
