d76a902c87 Further changes to the date/time functions to suppress harmless signed 
integer overflow warnings that could have occurred when doing out-of-range
date calculations which, according to the docs, give undefined results.

3edb157e23 The documentation says that the built-in date-time functions give undefined 
results for dates before 0000-01-01 and after 9999-12-31.  Change the
actually implementation so that the answer given is really NULL.  This also
avoids unnecessary hand-wringing over an signed integer overflow that might
otherwise occur when processing out-of-bound dates.

disable the query flattener is needed, but this will server for the time
being.
