Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time.
Remember that not all countries or even local areas use Daylight Saving Time.
The time calibration signals transmitted from Mainfl ingen (Germany), Anthorn (England), or Fort Collins
(the United States) include both Standard Time and DST data.
Note that an
x AUTO setting (Auto STD or Auto DST) will be indicated only if the currently selected city
code is one that supports calibration time signal reception. While AUTO is selected, the watch will
switch between STD and DST automatically in accordance with time calibration signal data.
The initial default setting is
x AUTO when any one of the following city codes is selected as the Home
City code: LONDON (LON), PARIS (PAR), ATHENS (ATH), NEW YORK (NYC), CHICAGO (CHI),
DENVER (DEN), LOS ANGELES (LAX), ANCHORAGE (ANC), or TOKYO (TYO).
For information about manually overriding the time calibration STD/DST setting, see “To manually
x
override a time calibration standard time/daylight saving time setting” (page E-30).
Note that you cannot switch between x STD (standard time) and DST (daylight saving time) while UTC*
is selected as your Home City.
Coordinated Universal Time, the world-wide scientifi c standard of timekeeping. The reference point for *
UTC is Greenwich, England.
If you experience problems receiving the time calibration signal in your area, it probably is best to
x
switch between Standard Time and Daylight Saving Time (summer time) manually (page E-30).
