Vernon Cole claimed to me that we need a new time zone for West Wendover, Nevada. After checking the case I think he is right.
 
West Wendover lies close to Wendover, Utah, but according to state border application they are on Pacific time while Wendover is on Mountain time. West Wendover seems to have a history long back of using Mountain time for convenience, but that use was never official. The main reason is that every most relations to other geographic locations close-by will be using Mountain time, and the bigger cities on the Nevada region are 100 miles or more from West Wendover. Apparently real problems began in the eighties and nineties when the city council began to insist on using Pacific time officially. In 1999 the DOT approved an application from West Wendover about shifting to Mountain time officially and on a permanent basis, using DST etc. The exact moment of application was opportune, the 31.st. of October 1999 at 2:00 PDT (GMT-7) when most of Nevada went back to PST (GMT-8) then West Wendover just stayed on GMT-7 (Mountain Standard Time).
 
The case of the Nevada northern border (Jackpot, Owyhee, and Mountain City), which is also using Mountain time is different, because they seem to have been using Mountain time "always" so they can use time zone America/Denver.
 
The legislation is resumed here:
