Usage guidelines
When the system time source is the local system time, the system time varies by the following items:
•
Local time zone.
•
UTC time.
•
Daylight saving time.
To view the system time, use the display clock command.
The correct system time setting is essential to network management and communication. Set the
system time correctly or use NTP or PTP to synchronize the device with a trusted time source before
you run it on the network.
Examples
# Set the system time ahead 1 hour for the period between 06:00:00 on 08/01 and 06:00:00 on
09/01.
