The advantage of using yyyy-mm-dd, beside the fact it is a standard, is that it is unambiguous. When I read a date like 12-11-2013, I don't know if we're talking about the 12th of november as we French correctly write it, or about the 11th of december as those bloody arrogant US American incorrectly do. But 2013-11-12 is non-ambiguous since (I guess) nobody uses a yyyy-dd-mm format.
