NAME

std::chrono::year_month_weekday::operatorsys_days,std::chrono::year_month_weekday::operatorlocal_days - std::chrono::year_month_weekday::operatorsys_days,std::chrono::year_month_weekday::operatorlocal_days

Synopsis

constexpr operator std::chrono::sys_days() const noexcept; (1) (since C++20)
explicit constexpr operator std::chrono::local_days() const noexcept; (2) (since C++20)

Converts *this to a std::chrono::time_point representing the same date as this year_month_weekday.
1) If year().ok() && month().ok() && weekday().ok():

      * If index() == 0, returns a sys_days that represents the date 7 days prior to the first weekday() of the year and month.
      * Else, returns a sys_days that represents the date (index() - 1) * 7 days after the first weekday() of the year and month.

Otherwise, the returned value is unspecified.
2) Same as (1), but returns local_days instead of sys_days. Equivalent to local_days(sys_days(*this).time_since_epoch()).
