template<class Duration> staticstd::chrono::sys_time<std::common_type_t<Duration,std::chrono::seconds>> to_sys(conststd::chrono::utc_time<Duration>& t);		(since C++20)

Converts autc_timet to asys_time representing the same point in time (if possible).

Ift represents a time point during a leap second insertion, the last representable value ofsys_time prior to the insertion of the leap second is returned. In all other cases,utc_clock::from_sys(utc_clock::to_sys(t))== t.

[edit]Return value

Asys_time representing the same point in time ast, or the last representable value prior to the insertion of the leap second ift represents a time point during a leap second insertion.
