Time zone

Time zone
Based on Coordinated Universal Time (UTC), the
standard time commonly used is adopted by countries
and regions around the world.
Standard time is determined by nations and regions,
with "time zone" used to refer to the whole of a
region that uses the same standard time. At present,
the globe is divided into 38 time zones (as of October
2022).
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.
The adoption and duration of daylight saving time
vary depending on the country.
 DST (daylight saving time or "summer time") in each region may be
changed by countries and regions.

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.
