Parameters

zone-name: Specifies a time zone by its name, a case-sensitive string of 1 to 32 characters.

add: Adds an offset to the UTC time.

minus: Decreases the UTC time by an offset.

zone-offset: Specifies an offset to the UTC time, in the hh:mm:ss format. The hh value is in the range of 0 to 23, the mm value is in the range of 0 to 59, and the ss value is in the range of 0 to 59. The leading zero in a segment can be omitted. If the seconds segment is 0 (hh:mm:00), you can omit it. If both the minutes and seconds segments are 0 (hh:00:00), you can omit both of the segments. For example, to specify 08:00:00, you can enter 8.

Usage guidelines

The local time zone, together with the UTC time and daylight saving time, determines the system time. You can use the display clock command to view the system time.

A correct system time setting is essential to network management and communication. Set the system time correctly or use NTP to synchronize your device with a trusted time source before you run it on the network.

Examples

# Set the name of the local time zone to Z5, and add 5 hours to the UTC time.

<Sysname> system-view
[Sysname] clock timezone Z5 add 5
