Discrepancies between official UTC+07:00 and geographical UTC+07:00

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 zones=

Historical time offsets

File:ROC-TimeZones.svg

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 Xikang and Qinghai, central Outer Mongolia (1921–1924), and all of Yunnan, Guangxi, Guizhou, Ningxia, Suiyuan, Gansu, Sichuan, and Shaanxi.
