Daylight-Savings timing includes some border cities in México
Northern Mexican Border's New Daylight Saving Plan
Published 11-Dec-2009. Changed 9-Mar-2010
Northern Mexico’s border cities will soon share the same daylight saving schedule as the United States. The new DST schedule will see these border cities extending their daylight saving time (DST) to last from the second Sunday of March to the first Sunday of November, which is in line with the United States’ DST schedule.
Mexico’s Chamber of Deputies, as well as the Senate, have both approved a proposal for northern Mexico’s border cities to share the same daylight saving schedule with the United States. The synchronized schedule for the border cities will begin on Sunday, March 14, 2010.

Above is a map showing northern regions in Mexico that will share the same daylight saving schedule as the USA. These parts are highlighted in pink or within the dashed area and are numbered on the map. Note: the dashed lines are an indicative display of the areas roughly 20 kilometers from and within the Mexican side of the US/Mexican border.
