*Effects*: Equivalent to:return os << format(os.getloc(), *STATICALLY-WIDEN*<charT>("{:L%T}"), hms);

[*Example [1](#example-1)*: for (auto ms : {-4083007ms, 4083007ms, 65745123ms}) { hh_mm_ss hms{ms};
 cout << hms << '\n';} cout << hh_mm_ss{65745s} << '\n';

Produces the output (assuming the "C" locale):-01:08:03.00701:08:03.00718:15:45.12318:15:45
