`timezone_names`

.. versionadded:: 3.5

The ``timezone_names`` function was added in Twig 3.5.

The timezone_names function returns the names of the timezones:

.. code-block:: twig

{# Acre Time (Eirunepe), Acre Time (Rio Branco), ... #}
{{ timezone_names()|join(', ') }}

By default, the function uses the current locale. You can pass it explicitly:

.. code-block:: twig

{# heure : Antarctique (Casey), heure : Canada (Montreal), ... #}
{{ timezone_names('fr')|join(', ') }}

.. note::

The ``timezone_names`` function is part of the ``IntlExtension`` which is not
installed by default. Install it first:

.. code-block:: bash

    $ composer require twig/intl-extra

Then, on Symfony projects, install the ``twig/extra-bundle``:

.. code-block:: bash

    $ composer require twig/extra-bundle

Otherwise, add the extension explicitly on the Twig environment::

    use Twig\Extra\Intl\IntlExtension;

    $twig = new \Twig\Environment(...);
    $twig->addExtension(new IntlExtension());
