std::chrono::operator<< (std::chrono::sys_time)

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.

to_stream (std::chrono::sys_time) (C++20)	outputs a sys_time into a stream according to the provided format (function template)
operator<<	outputs a `year_month_day` into a stream (function template)

std::chrono::operator<< (std::chrono::sys_time)

Return value
