Be fussier about setting tst_QDateTime's globals.

Time zones change on the whim of politicians.  Consequently, we can
seem to be in CET/CEST or on UTC (because we tested sample dates when
our zone coincided) when we aren't (i.e. we're in a materially
different zone at the time probed by some particular test).  Make the
initialization of the globals that test this more robust against
governmental meddling and document the unfixable problem with Algeria:
a DST transition *on the epoch*.
