Contains the implementation details of the implementation-defined behavior in libc++. Implementation-defined is mandated to be documented by the Standard.
Updating the Time Zone Database¶
The Standard allows implementations to automatically update the remote time zone database. Libc++ opts not to do that. Instead calling
std::chrono::remote_version()will update the version information of the remote time zone database,
std::chrono::reload_tzdb(), if needed, will update the entire remote time zone database.
This offers a way for users to update the remote time zone database and give them full control over the process.

The order of the entries matches the entries in the draft of the Standard.
