Yes, I've been bitten by this as well :-)

I think you're stuck with the extra validation step, but you can do it quite
neatly with a replacement function that looks something like this:
function myCheckdate ($m, $d, $y, $min = 1900, $max = 2100)
{
// check whether $y is within allowable range
if ($y <= $min || $y >= $max)
return false;
// the year is OK: checkdate can do its stuff
return (checkdate($m, $d, $y))
}
You can adjust the default allowable years to match what you usually need,
and then override them as necessary.
Personally I'd like to see PHP's checkdate() work a bit like the one above,
or maybe have checkReasonableDate() and checkImprobableDate(): I'm prepared
to believe that some PHP developers need to validate three- and five- digit
years, but I can't believe that it's *that* common :-)
Cheers
