@htmlinclude pkg-marker-core.html A MIRIAM-compliant date representation.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * A Date object stores a reasonably complete representation of date and
 * time.  Its purpose is to serve as a way to store dates to be read and
 * written in the <a target='_blank'
 * href='http://www.w3.org/TR/NOTE-datetime'>W3C date format</a> used in
 * RDF Dublin Core annotations within SBML.  The W3C date format is a
 * restricted form of <a target='_blank'
 * href='http://en.wikipedia.org/wiki/ISO_8601'>ISO 8601</a>, the
 * international standard for the representation of dates and times.  A
 * time and date value in this W3C format takes the form
 * YYYY-MM-DDThh:mm:ssXHH:ZZ (e.g., <code>1997-07-16T19:20:30+01:00</code>)
 * where XHH:ZZ is the time zone offset.  The libSBML Date object contains
 * the following fields to represent these values:
 * 
 * @li @em year: a long integer representing the year.  This should be a
 * four-digit number such as @c 2011.
 * 
 * @li @em month: a long integer representing the month, with a range of
 * values of 1&ndash;12.  The value @c 1 represents January, and so on.
 *
 * @li @em day: a long integer representing the day of the month, with a
 * range of values of 1&ndash;31.
 * 
 * @li @em hour: a long integer representing the hour on a 24-hour clock,
 * with a range of values of 0&ndash;23.
 * 
 * @li @em minute: a long integer representing the minute, with a range
 * of 0&ndash;59.
 * 
 * @li @em second: a long integer representing the second, with a range
 * of 0&ndash;59.
 * 
 * @li @em sign: a long integer representing the sign of the offset (@c 0
 * signifying @c + and @c 1 signifying @c -).  See the paragraph below for
 * further explanations.
 * 
 * @li @em hours @em offset: a long integer representing the time zone's hour
 * offset from GMT, with a range of 0&ndash;12.
 * 
 * @li @em minute @em offset: a long integer representing the time zone's
 * minute offset from GMT, with a range of 0&ndash;59.
 *
 * To illustrate the time zone offset, a value of <code>-05:00</code> would
 * correspond to USA Eastern Standard Time.  In the Date object, this would
 * require a value of @c 1 for the sign field, @c 5 for the hour offset and
 * @c 0 for the minutes offset.
 *
 * In the restricted RDF annotations used in SBML, described in
 * Section&nbsp;6 of the SBML Level&nbsp;2 and Level&nbsp;3 specification
 * documents, date/time stamps can be used to indicate the time of
 * creation and modification of a model.  The following SBML model fragment
 * illustrates this:

 * should be a four-digit number such as @c 2011.
 * 
 * @li @em MM is a two-digit integer representing the month, with a range
 * of values of 01&ndash;12.  The value @c 1 represents January, and so
 * on.
 *
 * @li @em DD is a two-digit integer representing the day of the month,
 * with a range of values of 01&ndash;31.
 * 
 * @li @em T is the literal character @c T.
 * 
 * @li @em hh is a two-digit integer representing the hour on a 24-hour
 * clock, with a range of values of 00&ndash;23.
 * 
 * @li @em mm is a two-digit integer representing the minute, with a
 * range of 00&ndash;59.
 * 
 * @li @em ss is a two-digit integer representing the second, with a
 * range of 0&ndash;59.
 * 
 * @li @em X is the the sign of the time zone offset, either @c + or
 * <code>-</code>.
 *
 * @li @em HH is a two-digit integer representing the hour of the time
 * zone offset, with a range of 00&ndash;23.
 *
 * @li @em ZZ is a two-digit integer representing the minutes of the time
 * zone offset, with a range of 00&ndash;59.
 *
 * In the string format above, it is important not to forget the literal
 * character @c T in the string.  Here is an example date/time string:
 * <code>1997-07-16T19:20:30+01:00</code>, which would represent July 16,
 * 1997, at 19:20:30 in Central European Time (which is UTC +1:00). 
   *
   * If this method is given a @c null argument or a string of length zero,
   * it constructs a Date object with the value of January 1, 2000, at time
   * 00:00 UTC.  Otherwise, the argument @em must be in the complete format
   * described above, or unpredictable results will happen.
   *
   * @param date a string representing the date.
   *
   *
 * @return integer value indicating success/failure of the
 * function.  @if clike The value is drawn from the
 * enumeration #OperationReturnValues_t. @endif The possible values
 * returned by this function are:
 * @li @link libsbml#LIBSBML_OPERATION_SUCCESS LIBSBML_OPERATION_SUCCESS@endlink
   * @li @link libsbml#LIBSBML_INVALID_ATTRIBUTE_VALUE LIBSBML_INVALID_ATTRIBUTE_VALUE@endlink
