STD/DST Switching
You can select summer time or standard time independently for each city. The initial
default setting for all cities is AT (AUTO).
Normally you should use the AT (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 a time of a location that is not included in the watch's list of 29 cities
− When the preset AUTO standard time/summer time timing is incorrect for some
reason
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.
Note that you cannot switch between 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.
