 -- Test shorthand input values
 -- We can't just "select" the results since they aren't constants; test for
 -- equality instead.  We can do that by running the test inside a transaction
 -- block, within which the value of 'now' shouldn't change.  We also check
 -- that 'now' *does* change over a reasonable interval such as 100 msec.
 -- NOTE: it is possible for this part of the test to fail if the transaction
 -- block is entered exactly at local midnight; then 'now' and 'today' have
 -- the same values and the counts will come out different.
