I found this corroboration:

CA: Winterhaven California, in deference to its proximity to Yuma AZ,
observes Mountain Standard Time year round. This means that (like AZ)
Winterhaven does not observe Daylight Saving time. So this puts
Winterhaven ahead of California by one hour (in sync with Arizona)
during Standard time - in the Fall and Winter. And in sync with both CA
and AZ during Spring and Summer (Daylight Saving time). The dividing
line of this observed boundary is locally considered to be the "All
American Canal".
CA: Earp/Vidal California, in deference to its proximity to Parker AZ,
observes Mountain Standard Time year round. This means that Earp and the
surrounding area does not observe Daylight Saving time. So this puts
Earp ahead of CA by one hour (in sync with AZ) during Standard time - in
the Fall and Winter. And in sync with both CA and AZ during Spring and
Summer (Daylight Saving time). The dividing line of this observed
boundary is estimated, but it is reported to extend to somewhere between
Vidal and Vidal Junction.

What we still need is information about when this has started, or
whether it was forever like this.
Can you search?

I'm in Las Vegas at the moment, but am thinking of going to the AFA
conference in Phoenix, AZ this Sept. I might have the opportunity to drive
through that area in between and ask the Vidal locals about this.
Sincerely,
