Most of Mexico no longer observes daylight saving time (DST; Spanish: horario de verano) as it was abolished on Sunday, 30 October 2022 The exceptions are the entire state of Baja California, as well as the border municipalities in Chihuahua, Coahuila, Nuevo León, and Tamaulipas which still observe daylight savings time matching the schedule of the United States beginning on the second Sunday of March and ending on the first Sunday of November.
So now if I chose mexico city zone, it is one hour ahead so the shedule time for the widget is not working properly
to work properly I have to select Mazatlan México UTC.
