/*
   This very simple applet lets the user type dates into an
   input box.  The input strings are parsed by a constructor from the
   Date class.  If the input is acceptable as a date/time, then the
   date/time is displayed.  If not, an error message is displayed.
   At the start, the current date and time are displayed.
