Configuring Time Clocks and Time Zone
The following options are available:
• zone — the time zone code for daylight saving time
• week (recurring only)— the week of the month on which daylight saving begins (week1) and ends
(week2)
• day (recurring only) — the day of the week on which daylight savings begin (day1) and ends (day2)
• date (non-recurring only) — the date of the month on which daylight saving begins (date1) and ends
(date2)
• month — the month in which daylight saving begins (month1) and ends (month2)
• year (non-recurring only) — the year in which daylight saving begins (year1) and ends (year2)
• offset — the difference in minutes between standard time and daylight saving time.
Default = 60 minutes
Guidelines
General guidelines for configuring daylight saving time transitions:
• Specify the time zone code for daylight saving time.
• recurring — specify a day of the month (week#|first|last/day of the week/month).
• not recurring — specify a date (month/day of the month/year).
• Define two days:
–
Day1 = beginning of daylight saving time.
–
Day2 = end of daylight saving time.
• In the Southern hemisphere, month2 must be before month1, as daylight saving time begins in the
fall and ends in the spring.
• Specify the exact time that the transition should occur (24 hour clock).
–
Time of transition into daylight saving time — according to local standard time.
–
Time of transition out of daylight saving time — according to local daylight savings time.
• For the clock summer-time recurring command, the default values are the United States transition
rules:
–
Daylight saving time begins: 2:00 (AM) on the second Sunday of March.
–
Daylight saving time ends: 2:00 (AM) on the first Sunday of November.
How to Define Recurring Daylight Saving Time Transitions
Step 1 From the SCE(config)# prompt, type clock summer-time zone recurring [week1 day1 month1 time1
week2 day2 month2 time2 [ offset ]] and press Enter.
Configures daylight saving time to start and stop on the specified days every year.
