Mexico is doing away with daylight saving time; some border states will be an exception

Mexico’s Senate approved a measure early Wednesday eliminating daylight savings time in most of the country.

With the law’s passage, many in Mexico will be turning back their clocks for the last time this Sunday.

The bill was already approved by Mexico’s lower house of Congress and now must be signed by President Andrés Manuel López Obrador — a long-time critic of daylight savings.

Mexico implemented daylight saving in 1996. But in July, the president sent a reform to Congress, with the support of the nation’s health minister, who called standard time “God’s clock,” and warned that the twice-a-year time change could be bad for people’s health.

The new law will permit some border states and cities to continue using daylight saving. But Sonora, like Arizona, already ignores the practice.
