ProCurve switches provide a way to automatically adjust the system clock for
Daylight Savings Time (DST) changes. To use this feature you define the month
and date to begin and to end the change from standard time. In addition to the
value “none” (no time changes), there are five pre-defined settings, named:
■ Alaska
■ Canada and Continental US
■ Middle Europe and Portugal
■ Southern Hemisphere
■ Western Europe
The pre-defined settings follow these rules:
Alaska:
• Begin DST at 2am on the second Sunday in March.
• End DST at 2am on the first Sunday in November.
Canada and Continental US:
• Begin DST at 2am on the second Sunday in March.
• End DST at 2am on the first Sunday in November.
