Hi, can somebody please review
https://github.com/dlang/phobos/pull/6366 ? Phobos currently
calls localtime() to handle timezones, which breaks insidiously
in multithreaded programs and occasionally silently returns wrong
times. localtime_r() support is not 100% universal, but
localtime() is universally wrong. (Except under Windows, where it
does the right thing and returns a threadlocal pointer. Go
figure.)
