     * TIMEVALUE.
     *
     * Returns a value that represents a particular time.
     * Use TIMEVALUE to convert a time represented by a text string to an Excel or PHP date/time stamp
     * value.
     *
     * 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:
     *        TIMEVALUE(timeValue)
     *
     * @param null|array|string $timeValue A text string that represents a time in any one of the Microsoft
     *                                    Excel time formats; for example, "6:45 PM" and "18:45" text strings
     *                                    within quotation marks that represent time.
     *                                    Date information in time_text is ignored.
     *                         Or can be an array of date/time values
     *
     * @return mixed 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
