STD/DST Switching
You can select summer time or standard time independently for each city. The initial default setting for all
cities is AUTO.
Normally you should use the AUTO setting because it automatically switches between summer time
and standard time. You should change the setting to STD (standard time) or DST (summer time) in the
following cases.
− When using the watch in a city not included in the City Code Table
− When the switching dates in your location are different from those shown in the City Code Table
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.
x Note that the
2
Second Hand always points to AUTO 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.
