 /**
  * Parses a ical date element.

  *   PROPERTY:YYYYMMDD[T][HH][MM][SS][Z]
  *   PROPERTY;VALUE=DATE:YYYYMMDD[T][HH][MM][SS][Z]
  *   PROPERTY;VALUE=DATE-TIME:YYYYMMDD[T][HH][MM][SS][Z]
  *   PROPERTY;TZID=XXXXXXXX;VALUE=DATE:YYYYMMDD[T][HH][MM][SS]
  *   PROPERTY;TZID=XXXXXXXX:YYYYMMDD[T][HH][MM][SS]
  *
  *   The property and the colon before the date are removed in the import
  *   process above and we are left with $field and $data.
  *
  * @param string $field
  *   The text before the colon and the date, i.e.
  *   ';VALUE=DATE:', ';VALUE=DATE-TIME:', ';TZID='
  * @param string $data
  *   The date itself, after the colon, in the format YYYYMMDD[T][HH][MM][SS][Z]
  *   'Z', if supplied, means the date is in UTC.
  *
  * @return array
  *   $items array, consisting of:
  *      'datetime'   => date in YYYY-MM-DD HH:MM format, not timezone adjusted
  *      'all_day'    => whether this is an all-day event with no time
  *      'tz'         => the timezone of the date, could be blank if the ical
  *                      has no timezone; the ical specs say no timezone
  *                      conversion should be done if no timezone info is
  *                      supplied
  *  @todo
  *   Another option for dates is the format PROPERTY;VALUE=PERIOD:XXXX. The
  *   period may include a duration, or a date and a duration, or two dates, so
  *   would have to be split into parts and run through date_ical_parse_date()
  *   and date_ical_parse_duration(). This is not commonly used, so ignored for
  *   now. It will take more work to figure how to support that.
