string2date()
Description
      This function evaluates the date string passed in t
      using the format string passed in format and uses
      the centurybase information from the locale
      information if the year is provided as a 2-digit year. The locale
      information will also be used if the format string indicates the month is
      not provided as digits. From all of that an attempt will be made to
      determine the date provided and assign it to a new date
      object, which is then returned. The return value will normally be the
      date that corresponds to the values passed. If problems occur parsing the
      date, then an incorrect date or even a non-initialized
      (.nul) date object may be returned.
