template <class CharT, class Traits, class Duration>

std::basic_ostream<CharT, Traits>&
operator<<(std::basic_ostream<CharT, Traits>& os,

const std::chrono::sys_time<Duration>& tp);
(1) (since C++20)
template <class CharT, class Traits, class Duration>

std::basic_ostream<CharT, Traits>&
operator<<(std::basic_ostream<CharT, Traits>& os,

const std::chrono::sys_days& tp);
(2) (since C++20)

Outputs tp into the stream os.

1) Equivalent to:
auto const dp = std::chrono::floor<std::chrono::days>(tp);
os << std::chrono::year_month_day(dp) << ' ' << std::chrono::time_of_day(tp - dp);
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).
2) Equivalent to os << std::chrono::year_month_day(tp);

Return value

os.
