Daylight Savings Time Ends Sunday 10/26 in Mexico
The twice-yearly clock clash along the border begins at 2 a.m. Sunday when Mexico returns to standard time. The United States won't switch until a week later.
In the interim, there will be a one-hour time difference between California and Baja California, scrambling the schedules of the thousands of people who cross the border routinely.
Daylight-saving time ends Nov. 2 in the United States.
Until then, Tijuana will be one hour behind San Diego. For example, when the clock reads 7 a.m. in San Diego, it will be 6 a.m. in Tijuana.
While clocks are out of sync, the schedule for the fast-pass SENTRI lane at the Otay Mesa border crossing will be from 5 a.m. to 11 p.m. (California time) Monday through Friday, and from 5 a.m. to 1 a.m. (also California time) on weekends, according to U.S. Customs and Border Protection.
Regular traffic lanes at Otay Mesa will not be affected because they are open around the clock. Likewise, the San Ysidro crossing, including SENTRI lanes, is open 24 hour a day.
