Our research concluded that there is no known location in the state of Baja California that observes Mexican DST rules. All are on US DST rules. The 20km boundary mentioned in the law applies in the other Mexican states, but not in Baja California due to the exclusions mentioned in the same law.

One more data point in support of your conclusion: I reached out to a contact on Cedros Island, which nearly touches the southern border of Baja. He indicates that clocks on the island adjusted on November 1. Regards, Steve Jones Emacs!
