This fixes hex() so that it outputs the hex of the ASCII for the time data to make it aligned with MariaDB. It also fixes the following functions so that they use NOW() as a DATETIME with the input TIME added to it: * weekday() * yearweek() * monthname() * last_day() * year() * weekofyear() * week() * to_days() * quarter() * month() * dayofyear() * dayofweek() * dayofmonth() * day() * date()
