Returns the map for default time type.
If the version of MySQL is lower than 5.6.4, then the types will be without fractional seconds,
otherwise with fractional seconds.

@return array
Returns the map for default time type . If the version of MySQL is lower than 5 . 6 . 4 then the types will be without fractional seconds otherwise with fractional seconds .
