* PHPExcel is a lot more forgiving than MS Excel when passing non numeric values to this function. |
* A Month name or abbreviation (English only at this point) such as 'January' or 'Jan' will still be accepted, |
* as will a day value with a suffix (e.g. '21st' rather than simply 21); again only English language. |
* |
* @access public |
* @category Date/Time Functions |
* @param integer $year The value of the year argument can include one to four digits. |
* Excel interprets the year argument according to the configured |
* date system: 1900 or 1904. |
* If year is between 0 (zero) and 1899 (inclusive), Excel adds that |
* value to 1900 to calculate the year. For example, DATE(108,1,2) |
* returns January 2, 2008 (1900+108). |
* If year is between 1900 and 9999 (inclusive), Excel uses that |
* value as the year. For example, DATE(2008,1,2) returns January 2, |
* 2008. |
* If year is less than 0 or is 10000 or greater, Excel returns the |
* #NUM! error value. |
* @param integer $month A positive or negative integer representing the month of the year |
* from 1 to 12 (January to December). |
* If month is greater than 12, month adds that number of months to |
* the first month in the year specified. For example, DATE(2008,14,2) |
* returns the serial number representing February 2, 2009. |
* If month is less than 1, month subtracts the magnitude of that |
* number of months, plus 1, from the first month in the year |
* specified. For example, DATE(2008,-3,2) returns the serial number |
* representing September 2, 2007. |
* @param integer $day A positive or negative integer representing the day of the month |
* from 1 to 31. |
* If day is greater than the number of days in the month specified, |
* day adds that number of days to the first day in the month. For |
* example, DATE(2008,1,35) returns the serial number representing |
* February 4, 2008. |
* If day is less than 1, day subtracts the magnitude that number of |
* days, plus one, from the first day of the month specified. For |
* example, DATE(2008,1,-15) returns the serial number representing |
* December 16, 2007. |
