 # `leap_second` class
 
 A `leap_second` represents a date and a value for an inserted leap second. The library creates `leap_second` objects as part of its time zone database initialization. It provides **`const`** access to the created objects. You can't construct or copy a `leap_second` object, and use of the default move constructor or default move assignment operator results in undefined behavior.
 
-Microsoft C++ supports the `leap_second` class starting in Visual Studio 2019 version 16.10. The `leap_second` class is a C++20 feature. The [`/std:c++latest`](../build/reference/std-specify-language-standard-version.md) compiler option is required.
