Description:

From manual page: http://www.php.net/datetime.formats.date
---

In "Localized Notations" the 7th line says >>Day, month and two digit year, with dots or tabs 	dd [.\t] mm "." yy 	"30.6.08", "22\t12\t78"<<
The last example "22\t12\t78" does not match to the RegExp and is not accepted by the DateTime constructor (which is correct, but the example is not). The second tab must be a dot to meet the RegExp: "22\t12.78"
Implementation seems to be correct, but documentation/example must be maintained.

Test script:
---------------
function testDateTimeExample() {
    $mustBeValid = new DateTime("22\t12.78");
    try {
        $isInvalid = new DateTime("22\t12\t78");
    }catch(Exception $e){
        // log $e
    }
}
