There are other ways to get a consistent 'now' across an entire SQL
statement:
(1) Run "SELECT julianday('now')" separately, then bind the result into
your SQL statement in place of the 'now' strings.
(2) Enclose the date and time functions in a subquery: SELECT (SELECT
timestamp('now')), * FROM tab;
This issue is sufficiently obscure that it is not worth adding (and testing
and documenting and supporting forever) yet another pragma.
