There are time zone differences based on time offsets from Coordinated Universal Time (UTC), which has 

been internationally adopted. The world is divided into 24 time zones, and neighboring time zones have a 

one-hour time difference, so that they correspond to the rotation of the earth which makes one full rotation 

in 24 hours (1 day). In some regions of the world, daylight saving time is individually observed.

Daylight saving time is a system that advances the official local time by one hour during the summer to take 

advantage of longer daylight hours.

●List of time zone differences in major regions of the world

The time differences and use of daylight saving time in each region are subject to change according 

to the governments of the respective countries or regions.

Refer to "How to use the time difference adjustment function" on page 72.
