time zone name.

Temporarily set the time zone for the current thread.
This is a context manager that uses django.utils.timezone.activate()
to set the timezone on entry and restores the previously active timezone
on exit.
The ``timezone`` argument must be an instance of a ``tzinfo`` subclass, a
time zone name, or ``None``. If it is ``None``, Django enables the default
time zone.

Check if value is a datetime and converts it to local time if necessary.
If use_tz is provided and is not None, that will force the value to
be converted (or not), overriding the value of settings.USE_TZ.
This function is designed for use by the template engine.

Convert an aware datetime.datetime to local time.
Only aware datetimes are allowed. When value is omitted, it defaults to
now().
Local time is defined by the current time zone, unless another time zone
is specified.

Determine if a given datetime.datetime is aware.

Assuming value.tzinfo is either None or a proper datetime.tzinfo,
value.utcoffset() implements the appropriate logic.
