std::chrono...ock::to_sys(3)  C++ Standard Libary std::chrono...ock::to_sys(3)

NAME
       std::chrono::utc_clock::to_sys -	std::chrono::utc_clock::to_sys

Synopsis
	  template< class Duration >

	  static	    std::chrono::sys_time<std::common_type_t<Duration,
       (since C++20)
	  std::chrono::seconds>>

	  to_sys( const	std::chrono::utc_time<Duration>& t );

	  Converts a utc_time t	to a sys_time representing the same  point  in
       time (if
	  possible).

	  If  t	 represents  a	time point during a leap second	insertion, the
       last representable
	  value	of sys_time prior to the insertion of the leap second  is  re-
       turned. In all
	  other	cases, utc_clock::from_sys(utc_clock::to_sys(t)) == t.

Return value
	  A  sys_time  representing  the  same point in	time as	t, or the last
       representable value
	  prior	to the insertion of the	leap second if	t  represents  a  time
       point during a leap
	  second insertion.
