Time zone
Time zone
Based on Coordinated Universal Time (UTC), the standard time
commonly used is adopted by countries and regions around the world.
The standard time is determined by each country or region, and the
region where the same standard time is adopted is referred to as the
time zone, and presently, the time zone is divided into 40 zones.
DST (Daylight Saving Time)
Depending on the area, DST (Daylight Saving Time) 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.
 Daylight Saving Time is subject to change owing to circumstances of the country or region.

Coordinated Universal Time (UTC)
UTC is the universal standard time coordinated through an
international agreement. This is used as the official time for recording
time around the world. The time obtained by adding a leap second
to the “International Atomic Time (TAI)” determined based on the
atomic clock around the world and coordinated in order to compensate
for deviations from universal time (UT) which is astronomically
determined is the UTC.
 Each time zone is based on data as of January 2014.
 Please be advised that regions for which the time zone is changed thereafter cannot be
reflected.
 The time differences and use of daylight saving time in each city are subject to
change according to the governments of the respective countries or regions.
