    Converts the given object to a timezone aware datetime object.

    If a timezone aware datetime object is passed, it is returned unmodified.
    If a native datetime object is passed, it is given the specified timezone.
    If the input is a string, it is parsed as a datetime with the given timezone.

    Date strings are accepted in three different forms: date only (Y-m-d), date with time
    (Y-m-d H:M:S) or with date+time with microseconds (Y-m-d H:M:S.micro). Additionally you can
    override the time zone by giving a specific offset in the format specified by ISO 8601:
    Z (UTC), +HH:MM or -HH:MM.

    :param str|datetime input: the datetime or string to convert to a timezone aware datetime
    :param datetime.tzinfo tz: timezone to interpret ``input`` in
    :param str arg_name: the name of the argument (used in an error message)
