As far as I know, the position of the tzdata people is that while this
belief is held almost everywhere that does not observe DST but is
surrounded by places that do (I should know; I live in Indiana, which
was such a place until 2006), almost nowhere does it have any formal
legitimacy, and systems that use the data therefore, by design, will not
actually generate "CST/MDT" timestamps.

When exactly is this transition supposed to take place? At 2AM, Manitoba
springs forward, but Alberta remains on MST for another hour - nowhere
else in North America *but* Saskatchewan uses an offset of -06:00 for
this hour-long period.
