Installation

The recommended way to use this library is via Composer.

Composer

To add this package as a local, per-project dependency to your project, simply add a dependency on data-values/time to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on version 1.x of this package:

    {
        "require": {
            "data-values/time": "~1.2"
        }
    }

Manual

Get the code of this package, either via git, or some other means. Also get all dependencies. You can find a list of the dependencies in the "require" section of the composer.json file. Then take care of autoloading the classes defined in the src directory.

Tests

This library comes with a set up PHPUnit tests that cover all non-trivial code. You can run these tests using the PHPUnit configuration file found in the root directory. The tests can also be run via TravisCI, as a TravisCI configuration file is also provided in the root directory.

DataValues Time has been written by the Wikidata team, as Wikimedia Germany employees for the Wikidata project.
