Fred Condo 5954774530 BUGFIX: Use UTC consistently across all tests for date/time calculations
This ensures that tests will not pass or fail based on whether the test
machine is on NZ time.

This partially reverts df050eda5d, which has
already been merged. Instead of finding tests that use date calculations, we
are now setting the default time zone in SapphireTest so it will apply to the
whole test suite and any future tests.

Adjust expected values in certain tests for UTC, where the expected values had
previously been expressed in NZ time.

When creating a temp DB for test fixtures, create the DB connection with
timezone UTC.
