-------------------------------------------------------------------
To add to this, I believe that this can be tripped in
ArrayTypeTest.timestampArrays by setting the data size to 101
(AvaticaStatement.DEFAULT_FETCH_SIZE + 1).
The first 100 blocks are fine, but then the next one is off by as many hours as
my UTC offset.
So not only is the wrong calendar being used, different calendars are being
used for different frames.
