  ERROR CODE:  F

  MESSAGE TEXT:  ZONE argument to DATE_AND_TIME is too short (LEN=n),
  required LEN=5

  EXPLANATION:  The number of characters associated with the ZONE
  argument to the DATE_AND_TIME intrinsic was shorter than the
  required length.  You must increase the number of characters passed
  in for this argument to be at least 5 characters in length.  Verify
  that the DATE and TIME arguments also meet their minimum lengths.
