HP 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 the first Sunday on or after April 24th.
• End DST at 2am the first Sunday on or after October 25th.
Canada and Continental US:
• Begin DST at 2am the first Sunday on or after April 1st.
