    Value Name:
        DATE-TIME

    Purpose:
        This value type is used to identify values that specify a
        precise calendar date and time of day. The format is based on
        the ISO.8601.2004 complete representation.

    Format Definition:
        This value type is defined by the following notation:

        .. code-block:: text

            date-time  = date "T" time

            date       = date-value
            date-value         = date-fullyear date-month date-mday
            date-fullyear      = 4DIGIT
            date-month         = 2DIGIT        ;01-12
            date-mday          = 2DIGIT        ;01-28, 01-29, 01-30, 01-31
                                               ;based on month/year
            time               = time-hour time-minute time-second [time-utc]
            time-hour          = 2DIGIT        ;00-23
            time-minute        = 2DIGIT        ;00-59
            time-second        = 2DIGIT        ;00-60
            time-utc           = "Z"

        The following is the representation of the date-time format.

        .. code-block:: text

            YYYYMMDDTHHMMSS

    Description:
        vDatetime is timezone aware and uses a timezone library.
        When a vDatetime object is created from an
        ical string, you can pass a valid timezone identifier. When a
        vDatetime object is created from a Python :py:mod:`datetime` object, it uses the
        tzinfo component, if present. Otherwise a timezone-naive object is
        created. Be aware that there are certain limitations with timezone naive
        DATE-TIME components in the icalendar standard.

    Example:
        The following represents March 2, 2021 at 10:15 AM with local time:

        .. code-block:: pycon

            >>> from icalendar import vDatetime
            >>> datetime = vDatetime.from_ical("20210302T101500")
            >>> datetime.tzname()
            >>> datetime.year
            2021
            >>> datetime.minute
            15

        The following represents March 2, 2021 at 10:15 AM in New York:

        .. code-block:: pycon

            >>> datetime = vDatetime.from_ical("20210302T101500", 'America/New_York')
            >>> datetime.tzname()
            'EST'

        The following represents March 2, 2021 at 10:15 AM in Berlin:

        .. code-block:: pycon

            >>> from zoneinfo import ZoneInfo
            >>> timezone = ZoneInfo("Europe/Berlin")
            >>> vDatetime.from_ical("20210302T101500", timezone)
            datetime.datetime(2021, 3, 2, 10, 15, tzinfo=ZoneInfo(key='Europe/Berlin'))
