Configuring DST to Occur Every Year
To configure DST to occur every year on the CSS, use the recurring option with
the clock summer-time command. When you use the recurring keyword without
any other options, the CSS uses the United States (US) standard for DST with a
60 minute offset. US DST starts at 2 a.m. on the first Sunday of April and reverts
to standard time at 2 a.m. on the last Sunday of October. The syntax is:
clock summer-time name recurring
The name variable is a three-character name for the time zone that appears when
you use the show clock command during DST (for example, EDT, CDT, PDT).
For example to configure a zone named EDT to signify eastern daylight time
using the default US standard DST every year, enter:
# clock summer-time EDT recurring
When you display this configuration using the show clock command, the Summer
Time field displays 1 Sunday April 2:00 last Sunday October 2:00 60.
If you want to configure the CSS DST to occur every year on a different date or
time other than that of the US standard, you must enter the start and stop dates and
time for DST in the following syntax:
clock summer-time zone recurring start_week start_day start_month
hh:mm end_week end_day end_month hh:mm {offset}
The options are:
• zone - The three-character name to designate the time zone.
• start_week - The week of the month to begin DST. Enter a number from 1 to
4, or last.
• start_day - The day of the week to begin DST. Enter a day from Sunday to
Saturday.
• start_month - The month to begin DST. Enter a month from January to
December.
• hh:mm - The military format of time in hours and minutes. For example, to
enter 2 a.m., enter 02:00. For 2 p.m., enter 14:00.
• end_week - The week of the month to end DST. Enter a number from 1 to 4,
or last.
