 * Implementation for the DATEVALUE() Excel function.<p>
 * <b>Syntax:</b><br>
 * <b>DATEVALUE</b>(<b>date_text</b>)
 * <p>
 * The <b>DATEVALUE</b> function converts a date that is stored as text to a serial number that Excel
 * recognizes as a date. For example, the formula <b>=DATEVALUE("1/1/2008")</b> returns 39448, the
 * serial number of the date 1/1/2008. Any time element is ignored (see {@link TimeValue}).
 * Remember, though, that your computer's system date setting may
 * cause the results of a <b>DATEVALUE</b> function to vary from this example
 * <p>
 * The <b>DATEVALUE</b> function is helpful in cases where a worksheet contains dates in a text format
 * that you want to filter, sort, or format as dates, or use in date calculations.
 * <p>
 * To view a date serial number as a date, you must apply a date format to the cell. Find links to more
 * information about displaying numbers as dates in the See Also section.
