This code shows that strtotime does not recognize some dates that are in the correct format but invalid:

$bod = "1970-1-222";
echo "I think that $bod is timestamp " . strtotime($bod) . "<BR>";
echo "and that would be " . date("Y-n-d",strtotime($bod)). "<BR>";

The output is:

I think that 1970-1-222 is timestamp 19062000
and that would be 1970-8-10

The documentation says that strtotime should report -1 on a failure. Shouldn't this be a failure?

I'm marking this as duplicate of 19166, because IMO this is a documentation problem rather than a problem in the code.

Ok. Does this mean that strtotime() is *not* meant to pick up invalid date inputs and fail on them?

Marking this as dup of 18101 instead, this beast needs rewriting :)
