Structure which is used to represent datetime values inside MySQL.

rely on this (actually now usage of make_*() family relies on a bit weaker

restriction). Also functions that produce MYSQL_TIME as result ensure this.

value (time_type == MYSQL_TIMESTAMP_TIME) days and hour member can hold

bigger values.
