Discrepancies between official UTC+07 and geographical UTC+07Edit
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 places which, despite lying in an area with a "physical" UTC+07 time, actually use another time zone.
Conversely, there are areas that have gone for UTC+07, even though their "physical" time zone is UTC+08, UTC+06, or even UTC+05.
