   TD displays/sets an installed clock via ZSDOS/ZDDOS.  It obtains the system
Time  and Date with  a  DOS  Function 98  and, if  the installed  clock driver 
supports a set function, sets the Date and Time using DOS Function 99.

   TD can  be  configured  with ZNCFG.COM  to present  the time  in  either US 
(Sep 18, 1988) or European (18 Sep, 1988) format.   Likewise, the set function
accepts either the US MM/DD/YY or the European DD.MM.YY.
