In late 2022, the nation's clocks "fell back" for the last time, in restoration of permanent standard time.
This is incorrect because Mexico did not end all clock changes in 2022. The 2022 time-zone law kept seasonal clock changes for northern border municipalities, which were still changing clocks in 2024 and 2025.
Full reasoning
Mexico abolished seasonal clock changes for most of the country in 2022, but not for all of it. The 2022 Ley de los Husos Horarios en los Estados Unidos Mexicanos explicitly preserved a horario estacional for municipalities on the northern border. An official Senate summary of the law says that "únicamente se aplicará un horario estacional para los estados y municipios de la frontera norte," and notes that this border schedule runs from the second Sunday in March to the first Sunday in November.
That exception was still being applied after 2022. In an official 2024 press release, Mexico's customs agency (ANAM) stated that, under the 2022 law, 36 municipalities in five northern-border states had to set their clocks back one hour on November 3, 2024, and would remain on that schedule until March 9, 2025.
So it is wrong to say that Mexico's clocks "fell back" for the last time in late 2022. What ended in 2022 was nationwide seasonal DST for most of Mexico; border municipalities continued to change clocks afterward.
