  750. 			          http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
  751. 			          Note that by default AM/PM time formats ("tt" or "t") cannot be
  752. 			          used on computers with a 24-hour time format. To prevent error
  753. 			          messages, use /I24 to ignore "tt" or "t" (AM/PM) in specified input
  754. 			          and/or output format, and /O24 to append AM/PM to the string on
  755. 			          systems with 24-hour time format.
  756. 			          If specified, the initial date/time must be in "yyyy-MM-dd HH:mm"
  757. 			          or "yyyy-MM-dd HH:mm:ss" format; but with /D "yyyy-MM-dd" format is
  758. 			          accepted, and with /T "HH:mm" and "HH:mm:ss" formats are accepted.
  759. 			          If specified without captions, switch /L forces localized button
  760. 			          captions (e.g. "Cancel" button caption is "Annuleren" on Dutch
  761. 			          systems); if only a single custom caption is specified, the other
  762. 			          one is localized (e.g. with /L:"OK=Gaan" on Dutch systems, "OK"
  763. 			          button caption is "Gaan", "Cancel" button caption is "Annuleren").
  764. 			          The selected date and/or time are written to Standard Out if "OK"
  765. 			          is clicked, otherwise an empty string is returned.
  766. 			          Switches /D, /T and /DTO are mutually exclusive, as are /DMAX and
  767. 			          /DL, and /DMIN and /DE.
  768. 			          Return code 0 for "OK", 1 for (command line) errors, 2 for "Cancel".
