"Mexico president presents bill to eliminate daylight saving time"

"It's likely that the clocks won't change next year in most states"

"The bill only requires a simple majority to pass the federal legislature, meaning that it is likely to become law. 
With the support of its allies, the ruling Morena party commands a majority in both the lower and upper houses.

Energy Minister Rocío Nahle and Health Minister Jorge Alcocer appeared at the president’s morning press 
conference on Tuesday to present arguments in favor of getting rid of the twice-a-year time change......
.....................
However, God’s clock and health worries may not apply in parts of some northern states where clock changes have been 
synchronized with states in the southern U.S. to facilitate cross-border trade and other connections.
Energy Minister Nahle said on Tuesday that there would continue to be exceptions in some northern border municipalities."
