However, in much of Western and Central Europe, despite lying between those two meridians, UTC+01:00 is used similarly, there are European areas that use UTC, even though their physical time zone is UTC−01:00 (e.g. The UTC+00:00 time zone, were it determined purely by longitude, would consist of the area between meridians 7☃0'W and 7☃0'E. Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines. This is the greatest deviation from physical time for UTC+00:00 with no DST.ĭiscrepancies between use of UTC+00:00 as standard time rather than local solar time Colour
