leap_second_info struct

Call get_leap_second_info to get a leap_second_info. This type only has public data members. It doesn't have base classes or members other than the ones specified.

Syntax

struct leap_second_info; // C++20

Public members

Name	Description
is_leap_second	The is_leap_second member is true only if the specified time point occurs during the insertion of a positive leap second.
elapsed	The elapsed member holds the sum of all the leap seconds between the epoch date (the starting date from which the clock measures time) 1970-01-01 and the specified time. If is_leap_second is true, the leap second referred to by the specified time is included in the elapsed sum.

Requirements

Header: <chrono>

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 compiler option is required.

An international standards body specifies when new leap seconds should be accounted for. A database of these changes is available for Windows 10 version 1809 and later, and Windows Server 2019 and later.
