Due to some jurisdictions changing their zones and rules, it's possible
for a non-CET zone to accidentally match CET at a few tested moments but
be different a few years later or earlier. This would lead to tests
failing if run in the partially-aliasing zone (e.g. Algeria, Lybia). So
test thoroughly; ideally at every mid-winter or mid-summer in whose
half-year any test below assumes zoneIsCET means what it says. (Tests at
or near a DST transition implicate both of the half-years that meet
there.) Years outside the 1970--2038 range, however, are likely not
properly handled by the TZ-database; and QDateTime explicitly handles them
differently, so don't probe them here.

Again, rule changes can cause a TZ to look like UTC at some sample dates
but deviate at some date relevant to a test using localTimeType. These
tests mostly use years outside the 1970--2038 range for which TZ data is
credible, so we can't helpfully be exhaustive. So scan a sample of years'
starts and middles.

Even so, TZ=Africa/Algiers will fail fromMSecsSinceEpoch(-1) because it
switched from WET without DST (i.e. UTC) in the late 1960s to WET with DST
for all of 1970 - so they had a DST transition *on the epoch*. They've
since switched to CET with no DST, making life simple; but our tests for
mistakes around the epoch can't tell the difference between what Algeria
really did and the symptoms we can believe a bug might produce: there's
not much we can do about that, that wouldn't hide real bugs.
