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 Table 17)
. In the first column of this table,
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.

The system time does not
change until it falls into
the daylight saving time
range.

range:
The system time increases
by summer-offset.

If the original system time
plus summer-offset is
beyond the daylight saving
time range, the original
system time does not
change. After you disable
the daylight saving setting,
the system time
automatically decreases by
summer-offset.
