TDEV xAy-z [{A| B}] starttime [stopdate] [stoptime]
Use this command to display the TDEV information calculated on
the input modules. A|B specifies Clock A or Clock B. The default is
the selected clock output.
To perform a TDEV calculation, start and a stop time are required.
If none are specified in the command line, the time defaults to the
last 24 hours. If the stop time is not specified, the current time is
assumed.
This command displays the returned TDEV values and the window
sizes for which they are valid. The command also displays the start
and stop time for TDEV calculation.
TDEV xAy-z [{A|B}] HISTORY [count]
A|B specifies Clock A or Clock B. The default is the selected clock
output. This command displays the one-day TDEV history for the
last one to 100 days.

port.

Note: If you specify times and dates, TDEV displays that occurred
after the starting date and time and before the ending date and time.
Specified dates have the format yyyy-mm-dd, and specified times
have the format hh:mm:ss.
Specified dates and times are not provided in ISO timestamp format,
and are separated by a space. Start time and stop time both default to
the current time of day. Stop date defaults to the current date. Start
date defaults to the current date, minus 24 hours.
