Reynosa and McAllen, Texas are separated by the Rio Grande and connected by the International Bridge. On the Mexican side: Central Standard Time in winter (UTC-6), Central Daylight Time in summer (UTC-5). On the American side: the same. Border cities often end up keeping identical clocks with their counterparts because commerce demands it.

Mexico uses Central Time for Reynosa and the Tamaulipas border region, matching the US Central Time Zone on the other side. The synchronization facilitates the maquiladora industry: hundreds of assembly plants in Reynosa employ workers who commute across the border or who manufacture for US companies. The supply chain runs on a shared clock.

Reynosa at 26 degrees north is Sonoran Desert country. Summers are intensely hot, easily reaching 40 degrees Celsius. Winters are mild. The city is flat and sprawling, a product of rapid industrial growth from the 1970s onward as maquiladoras multiplied along the border.

The Rio Grande, the border itself, has shrunk. Water withdrawals for agriculture and cities have reduced it substantially from its historical flow. The river that marks the time zone boundary between two nations is thinner than it used to be.
