Changing The System Time; Configuration Guidelines - HP 830 Series Configuration Manual

To configure the device name:
Step
1. Enter system view.
2. Configure the device name.

Changing the system time

You must synchronize your device with a trusted time source by using NTP or changing the system time
before you run it on the network. Network management depends on an accurate system time setting,
because the timestamps of system messages and logs use the system time. For NTP configuration, see
Network Management and Monitoring Configuration Guide.
In a small-sized network, you can manually set the system time of each device.

Configuration guidelines

You can change the system time by configuring the relative time, time zone, and daylight saving time. The
configuration result depends on their configuration order (see
1 represents the clock datetime command, 2 represents the clock timezone command, and 3 represents
the clock summer-time command. To verify the system time setting, use the display clock command. This
table assumes that the original system time is 2005/1/1 1:00:00.
