[Hank W.]

Is that a rule of the Russian Federation only, or can we apply it to the Falkland Islands?

The usual practice has been to not set the DST flag for time offsets that are permanent, or are the least of multiple offsets are used in one or more years.
Some judgment is needed, as there's not always a sharp line between "permanent" and "temporary" (was the U.S.
on permanent DST from 1942 to 1945, or was that temporary?) but the current Russian situation seems relatively permanent, so the DST flag isn't set there.
