- * PHPExcel is a lot more forgiving than MS Excel when passing non numeric values to this function.
254
- * A Month name or abbreviation (English only at this point) such as 'January' or 'Jan' will still be accepted,
255
- * as will a day value with a suffix (e.g. '21st' rather than simply 21); again only English language.

257
- * @access public
258
- * @category Date/Time Functions
259
- * @param integer $year The value of the year argument can include one to four digits.
260
- * Excel interprets the year argument according to the configured
261
- * date system: 1900 or 1904.
262
- * If year is between 0 (zero) and 1899 (inclusive), Excel adds that
263
- * value to 1900 to calculate the year. For example, DATE(108,1,2)
264
- * returns January 2, 2008 (1900+108).
265
- * If year is between 1900 and 9999 (inclusive), Excel uses that
266
- * value as the year. For example, DATE(2008,1,2) returns January 2,
267
- * 2008.
268
- * If year is less than 0 or is 10000 or greater, Excel returns the
269
- * #NUM! error value.
270
- * @param integer $month A positive or negative integer representing the month of the year
271
- * from 1 to 12 (January to December).
272
- * If month is greater than 12, month adds that number of months to
273
- * the first month in the year specified. For example, DATE(2008,14,2)
274
- * returns the serial number representing February 2, 2009.
275
- * If month is less than 1, month subtracts the magnitude of that
276
- * number of months, plus 1, from the first month in the year
277
- * specified. For example, DATE(2008,-3,2) returns the serial number
278
- * representing September 2, 2007.
279
- * @param integer $day A positive or negative integer representing the day of the month
280
- * from 1 to 31.
281
- * If day is greater than the number of days in the month specified,
282
- * day adds that number of days to the first day in the month. For
283
- * example, DATE(2008,1,35) returns the serial number representing
284
- * February 4, 2008.
285
- * If day is less than 1, day subtracts the magnitude that number of
286
- * days, plus one, from the first day of the month specified. For
287
- * example, DATE(2008,1,-15) returns the serial number representing
288
- * December 16, 2007.
