What's your source for this information? CENAM 
<https://www.cenam.mx/hora_oficial/> says "el horario de verano inicia el primer 
domingo de abril a las 2h00 de la mañana, momento en el cual los relojes se 
adelantan una hora, y termina el último domingo de octubre a las 2h00 de la 
mañana, instante en el que los relojes se atrasan una hora." This suggests that 
daylight saving time ends at 02:00, not 03:00.
