Precautions on time zone adjustment
If the time zone is adjusted near a time zone boundary, the time of the adjacent time zone may be displayed.
In some areas the boundaries observed by the watch may not exactly correlate to the actual time zone markers on
the land. This does not indicate a malfunction. In this case, set the time zone in the manual time zone setting mode.

Depending on the area, Daylight Saving Time (DST) is individually set.
Daylight Saving Time means summer time, which is a system to lengthen
daylight time by advancing 1 hour when daylight time is long in summer. Daylight saving time has been
adopted in about 80 countries, mainly in Europe and North America. The adoption and duration of daylight
saving time vary depending on the country.
