To turn summer time on and off
1. In the World Time Mode, use the E and
B buttons to select the city whose
summer time setting you want to
change.
2. Hold down the A button for about two
seconds to toggle the summer time
setting for the currently displayed city on
and off.
• The “DST” indicator appears on the display and timekeeping is
advanced by one hour when summer time is turned on.
• You can turn summer time on or off independently for each World
Time Mode city. Note, however, that you cannot change the summer
time setting for the “GMT” (Greenwich Mean Time) zone.
• If you turn on summer time for the city that you are using for your
Home Time city, summer time is also turned on in the Timekeeping
Mode.
Summer time, or Daylight Saving Time (DST) as is it is called in
some countries, calls for setting clocks ahead one hour during the
summer season. Note that the use of summer time depends on
the country and even the local area.
