        Do not use ctime, since it has undefined behavior with
        out-of-range time stamps.  This fixes a bug where
        (current-time-string '(2814749767106 0)) would make Emacs dump
        core on 64-bit Solaris 8; the fix is to remove all uses of ctime
        from the Emacs source code.

Personally, I find it preposterous that we need to reinvent library
functions.  Isn't there a better (safer) library function, or a
combination thereof, that we could use instead of rolling our own?

Why not have Emacs test for an out-of-range time stamp before
calling ctime?
