This is going to be a headache for US presidential electi[o]n years! + # In the country, there have been several attempts made to adapt + # standard time with the object of arriving at a better use of + # daylight for social and economic activities. In December, 1981 a + # permanent time zone was decreed for the states of Campeche, Yucatan, + # and Quintana Roo, displacing them from the 90th to the 75th + # meridian. This disposition was annulled on December 2, 1982. + # + # In 1988 a Summer Time was established for the states of Tamaulipas, + # Nuevo Leon, Coahuila, and Durango, which meant that from the first + # Sunday in April to the last [Sunday] of October those states + # displaced their time from the 90th to the 75th meridian.
