I wasn't aware that localtime was declared deprecated. Is
this true?

Yes. You can see the declaration in the error message. The
question you haven't asked is WHO declared it deprecated. The
answer is Microsoft (because if used carelessly, localtime can
overflow a buffer).

Can it? I don't think so. On the other hand, there is no way
to use it at all in a multithreaded environment. Which raises
an interesting question: if C++ adopts threading as part of the
language, do we also adopt this TR? Or?
