UTC+07:00 is an identifier for a time offset from UTC of +07:00. In ISO 8601 the associated time would be written as 2023-02-06T00:28:10+07:00. It is 7 hours ahead of UTC, meaning that when the time in UTC areas is midnight (00:00), the time in UTC+07:00 areas would be 7:00 in the morning.

Discrepancies between official UTC+07:00 and geographical UTC+07:00Edit
Since legal, political, and economic in addition to physical or geographical criteria are used in the drawing of time zones, it follows that official time zones do not precisely adhere to meridian lines. The UTC+07:00 time zone, were it drawn by purely geographical terms, would consist of exactly the area between meridians 97°30′ E and 112°30′ E. As a result, there are places which, despite lying in an area with a "physical" UTC+07:00 time, actually use another time zone. Conversely, there are areas that have adopted UTC+07:00, even though their "physical" time zone is UTC+08:00, UTC+06:00, or even UTC+05:00.
Areas within UTC+07:00 longitudes using other time zonesEdit

Historical time offsetsEdit
The Republic of China's offset for this time zone was Kansu-Szechwan, and was used until 1949, when the Chinese Communist Party took control of Mainland China following the Chinese Civil War and made UTC+08:00 the standard time for all areas under its control. Formerly, from 1918 to 1949, this time offset was used in eastern Sikang and Tsinghai, central Outer Mongolia (1921–1924), and all of Yunnan, Kwangsi, Kweichow, Ningsia, Suiyuan, Kansu, and Shensi.
