Usage Guidelines

Usage Scenario

You can run the display clock command to view the system date and clock setting and adjust the setting if necessary.

Precautions

The system clock is set using the clock datetime, clock timezone, and clock daylight-saving-time commands.

  • If the three commands are not used, the original system clock is displayed after you run the display clock command.
  • You can use any combination of the three commands to configure the system time. Table 1 lists the formats of the configured time.
The table assumes that the original system time is 08:00:00 on January 1, 2010.
  • 1: indicates that the clock datetime command is used, in which the current time and date is date-time.
  • 2: indicates that the clock timezone command is used, in which the time zone parameter is set and the time offset is zone-offset.
  • 3: indicates that the clock daylight-saving-time command is used, in which the DST parameters are set and the time offset is offset.
  • [1]: indicates that the clock datetime command is optional.
