Discrepancies between official UTC+07 and geographical UTC+07
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 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 Asian locales that despite lying in an area with a "physical" UTC+07 time, actually use another time zone.
Conversely, there are Asian areas that have gone for UTC+07, even though their "physical" time zone is UTC+06 (western most part of Indonesia).
Areas located within UTC+07 longitudes using other time zones
- Many parts of China, including for example Guangxi Province and Hainan Island
- Most of central Mongolia including the capital Ulaanbaatar
- Peninsular Malaysia
- Western part of Sarawak in Malaysian Borneo including Kuching
Areas located outside UTC+07 longitudes using UTC+07 time
Areas between 82°30′ W and 97°30′ E ("physical" UTC+06)
- The westernmost part of Indonesia including Banda Aceh.
Areas between 102°30′ W and 117°30′ E ("physical" UTC+08)
