D. S.T. execution time
At 2:00 a.m. on the first day of summer time, the clock
automatically gains one hour to show 3:00 a.m. When 2:00
a.m. comes on the last day of the summer time period, it loses
one hour and returns to 1:00 a.m.
Setting D. S.T.
Example:
Start date Sunday, March 25, 2001
End date Sunday, October 28, 2001
If set as the above, the unit remembers the start date as the
last Sunday of March and the end date as the last Sunday of
October. Once set, the unit automatically updates the settings
every year thereafter. No further manual setting is necessary.
