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.
