Configuring The Cumulative Offset Between The Utc And Tai; Configuring The Correction Date Of The Utc; Configuring The Parameters Of The Bits Clock - HP 5920 Configuration Manual

Configuring the cumulative offset between the UTC and TAI

The time displayed on a device is based on the Coordinated Universal Time (UTC). There is an offset
between UTC and TAI (International Atomic Time in English), which is made public periodically. This task
allows you to adjust the offset between the UTC and TAI on the device. It is applicable to the GM only.
To configure the cumulative offset between the UTC and TAI:
Step
1. Enter system view.
2. Configure the cumulative
offset between the UTC and
TAI.

Configuring the correction date of the UTC

This task allows you to adjust the UTC at the last minute (23:59) of the specified date.
To configure the correction date of the UTC:
Step
1. Enter system view.
2. Configure the correction date
of the UTC.

Configuring the parameters of the Bits clock

Clock nodes in a PTP domain exchange announce messages through BMC to elect a GM. They compare
the parameters in the announce messages in the following sequence: priority 1, time class, time accuracy,
and priority 2. If all these parameters are the same, the clock node with a smaller port ID (consisting of
clock number and port number) wins.
To configure the clock parameters
Step
1. Enter system view.
2. Configure priority 1 of the
clock.
3. Configure the parameters of
the Bits clock.
4. Configure the time accuracy
of the Bits clock.
