From the referenced page...

"We can insert into column of type TIME the value such as '12:15' and
then obtain '12:15:00' making select, but we couldn't do the same with
dates."

Huh?  Minutes and seconds have a valid value of zero.  Months and days
don't.  Date types need to contain a valid date, and time types need
to contain a valid time.  Anything else seems like, well, MySQL.
