Enhance zeroblob tests to use the sqlite3_memory_highwater in order to double-check that no large allocations are occurring. (CVS 5217) check-in: e93079be user: drh tags: trunk

Convert the date/time functions to work with milliseconds since the julian epoch internally (instead of days since the epoch) in order to avoid problems with floating-point roundoff error. The interface is unchanged. (CVS 5215) check-in: ed35f8a9 user: drh tags: trunk
