-Custom PyAMS utilities
-======================
-
-PyAMS_utils provides a small set of utilities. You can create some of them as global utilities registered in
-the global components registry; other ones can be created manually by a site administrator and
-are then registered automatically.
-
-
-Server timezone
----------------
-
-To manage timezones correctly, and display datetimes based on current server timezone, all datetimes should
-be defined and stored in UTC.
-
-PyAMS_utils provides a :py:class:`ServerTimezoneUtility <pyams_utils.timezone.utility.ServerTimezoneUtility>` which
-allows you to assign a default timezone to your server.
-
-To display a datetime with correct timezone, you can use the :py:func:`tztime <pyams_utils.timezone.tztime>` function,
-which assign server timezone to the given parameter:
-
-.. code-block:: python
-
-    from datetime import datetime
-    from pyams_utils.timezone import tztime
-
-    now = datetime.utcnow()
-    my_date = tztime(now)  # converts *now* to server timezone
-
-We could imagine that datetimes could be displayed with current user timezone. But it's quite impossible to know
-the user timazone from a server request. The only options are:
-
-- you ask an authenticated user to update a timezone setting in his profile
-
-- you can include Javascript libraries which will try to detect browser timezone from their computer configuration, and
-  do an AJAX request to update data in their session.
-
-That should require an update of :py:func:`tzinfo` adapter to get timezone info from session, request or user profile.
