error: implicit instantiation of undefined template 'std::array<double, 4>'

std::array is used in chrono/timespan.cpp but there is no corresponding include:

wrkdirs/usr/ports/devel/cpp-utilities/work/cpp-utilities-5.24.3/chrono/timespan.cpp:74:18: error: implicit instantiation of undefined template 'std::array<double, 4>'

I actually tested this with libc++ but only on GNU/Linux. Strange that it behaves differently with your version. I added the include. I suppose for easy fixes like that you could also just create a PR (instead of an issue).
