  This is the external declaration for the Pascal callable routine to convert
  a clunk value (64 bit integer) to the system_date and system_time format.
  This external declaration expects that the file 'CLUNK.TYP' has been 
  included at some point before this.

  How it works:
  You supply it a clunk value and it returns character arrays of containing
  the ASCII version of the date and time represented by the clunk value.
  The ascii date and time strings are preserved.

  Four valid "ids" statuses are possible:
   1 = success
  -1 = date prior to 1900
  -2 = date after 1999
  -3 = clunk overflow
}
