std::chrono::leap_second(3)

NAME
std::chrono::leap_second - std::chrono::leap_second

Synopsis
   Defined in header <chrono>
   class leap_second; (since C++20)
   The class leap_second represents the date and time of a leap second insertion.
   Users cannot construct leap_second objects except by copying from existing
   leap_second objects. The library implementation creates leap_second objects when it
   initializes the time zone database and provides const access to these objects.
   leap_second has a defaulted copy constructor and a defaulted copy assignment
   operator.

Member functions
