This command takes effect only when it is configured on the master clock node and the local clock of
the master clock node is the GM.
Specify either the
leap59-date
or
leap61-date
keyword in this command. If you execute this
command multiple times, the most recent configuration takes effect.
Examples
# Assume the current date is August 8, 2010. Specify the clock node type as BC for the device.
Adjust the UTC at the last minute of December 31, 2010 so that the UTC is one second slower than
the TAI.

Parameters
utc-offset
: Sets the cumulative offset between the UTC and TAI, in seconds. The
utc-offset
argument is in the range of 0 to 999.
Usage guidelines
A time difference exists between UTC and TAI. Internet devices typically use the UTC time. To
provide more accurate time, PTP also uses TAI. If the device acts as a subordinate clock node, it
uses the UTC time and TAI time of the clock reference. If the device acts as the clock reference, it will
calculate the TAI time based on the UTC time, and synchronize the UTC and TAI time to the
subordinate clocks. TAI provided by the device = Current UTC + cumulative offset.
BIPM periodically publishes the cumulative offset of UTC relative to TAI. Use the value published by
BIPM to configure this command.
You can configure this command only after you have specified a PTP profile and PTP mode for the
device.
This command takes effect only when it is configured on the master clock node and the local clock of
the master clock node is the GM.
