     * TIME.
     *
     * The TIME function returns a value that represents a particular time.
     *
     * NOTE: When used in a Cell Formula, MS Excel changes the cell format so that it matches the time
     * format of your regional settings. PhpSpreadsheet does not change cell formatting in this way.
     *
     * Excel Function:
     *        TIME(hour,minute,second)
     *
     * @param null|array|bool|float|int|string $hour A number from 0 (zero) to 32767 representing the hour.
     *                                    Any value greater than 23 will be divided by 24 and the remainder
     *                                    will be treated as the hour value. For example, TIME(27,0,0) =
     *                                    TIME(3,0,0) = .125 or 3:00 AM.
     * @param null|array|bool|float|int|string $minute A number from 0 to 32767 representing the minute.
     *                                    Any value greater than 59 will be converted to hours and minutes.
     *                                    For example, TIME(0,750,0) = TIME(12,30,0) = .520833 or 12:30 PM.
     * @param null|array|bool|float|int|string $second A number from 0 to 32767 representing the second.
     *                                    Any value greater than 59 will be converted to hours, minutes,
     *                                    and seconds. For example, TIME(0,0,2000) = TIME(0,33,22) = .023148
     *                                    or 12:33:20 AM
     *         If an array of numbers is passed as the argument, then the returned result will also be an array
     *            with the same dimensions
     *
     * @return array|DateTime|float|int|string Excel date/time serial value, PHP date/time serial value or PHP date/time object,
     *                        depending on the value of the ReturnDateType flag
     *         If an array of numbers is passed as the argument, then the returned result will also be an array
     *            with the same dimensions
