Outputs tp into the stream os.
1) Equivalent to:
This overload only participates in overload resolution if std::chrono::treat_as_floating_point_v<typename Duration::rep> is false and Duration(1) < std::chrono::days(1).
auto const dp = std::chrono::floor<std::chrono::days>(tp); os << std::chrono::year_month_day(dp) << ' ' << std::chrono::time_of_day(tp - dp);
2) Equivalent to os << std::chrono::year_month_day(tp);
Return value
os.
