Note about US & European Clock Times
Mexico’s central clock-time change dates are not usually synchronized with U.S. or European clock-time change dates, so if you’re traveling or scheduling appointments between Mexico, the US and Europe this spring and fall, double-check your times, especially as flights and other public transportation systems always operate their schedules using local time.
