Displaying the system time
The system time is determined by the commands clock datetime, clock timezone and clock summer-time.
If these three commands are not configured, the display clock command displays the original system time.
If you combine these three commands in different ways, the system time is displayed in the ways as
shown in
Table 13 . The numbers in the configuration column are described below:
• 1 indicates that the date-time has been configured with the clock datetime command.
• 2 indicates that the time-zone has been configured with the clock timezone command and the offset
time is zone-offset.
• 3 indicates that the daylight saving time has been configured with the clock summer-time
command and the offset time is summer-offset.
• [1] indicates that the clock datetime command is optional.
• The default system time is 2005/1/1 1:00:00 in the example.
