Unless they do something like the inverters to to product the cycles, the speed of rotation of the alternator is the governing factor on cycles. I
think-

Excerpt:
Much like a DC generator, an AC generator requires a coil to cut across the force lines of a magnetic field. This coil is attached to two slip rings,
which deliver the current to and from the load destination, thus completing the circuit. Alternating current generators are often called alternators.
During the first half turn, the coil cuts across the field near the magnet's north pole. Electrons travel up the wire, and the lower slip ring becomes
positively charged. When the coil cuts near the South Pole of the wire during the second half turn, the lower slip ring becomes negatively charged,
and electrons move down the wire. The faster the coil turns, the faster the electrons move, increasing the frequency (in Hertz) of the current
produced by the generator
It seems as though the speed of the generator governs the cycles. But in La Paz the time increase seems to be consistant, so I don't think the load
makes the difference, I think they just do not control the speed of the generator or possibly their RPM gauge is not correct.

From a Google seach
"Recently, a new type of power station has been developed in which the power needed to rotate the generating coil is supplied by a gas turbine
(basically a large jet engine which burns natural gas). In the United States and Canada the alternating emf generated by power stations oscillates at
$f=60$Hz, which means that the generator coils in power stations rotate exactly sixty times a second. In Europe, and much of the rest of the world,
the oscillation frequency of commercially generated electricity is $f=50$Hz."

In Europe, and much of the rest of the world, the oscillation frequency of commercially generated electricity is "f=50Hz".
And fluorescent lights actually turn off and on at the frequency speed. That's why some people get headaches when around fluorescents lights running
on 50 Hz. But that has nothing to do with the frequency in Baja.
It's a simple matter, really. Every generator has a certain amount of "slip" so that it can run in parallel with other generators. This means that
it's possible for one generator running at 61 Hz to "pull down" all the other generators. So all it would take is one bad frequency meter to cause the
problem.
Another scenario is that a mis-calibrated meter is on the main bus and is being used to set the speed of all the generators.
More than likely, it's a combination of both.
In the US, all meters have to be calibrated against a certified standard periodically. I doubt that is true in Baja.

I threw my clocks in the front yard. The only thing I notice now about time is the effect it has in the mirror.

Time to throw the mirrors in the front yard with the clocks.

I guess if you really need to know what time it is with any degree of accuracy, get one of those atomic clocks at COSTCO for about
$15.00.........actually, I am on fireman time....sleep till you are hungry, then eat till you are sleepy
