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

Converts asys_timet to autc_timeu that represents the same point in time.

u.time_since_epoch()- t.time_since_epoch() is equal to the number of leap seconds that was inserted betweent and 1 January 1970. Ift is the exact date of a leap second insertion, that leap second is counted as inserted.

[edit]Return value

Autc_time representing the same point in time ast.
