The User Defined Date field (cc=07) is also a 32-bit integer which may be  
encoded in a similar manner.  Possible uses are to indicate the date of last user  
zero and/or span calibration or possibly the date of next required calibration.  If  
this optional field is used, the user is responsible for correctly encoding the date 
into the appropriate 32-bit integer value.  Any modifications of this field (using  
the Download Internal Coefficients (‘v’) command) will result in the new value 
automatically being entered to transducer non-volatile memory. 
 
 
 
 The 
Date of Factory Calibration field (cc=08) identifies the date of factory  
  calibration for the DH200 transducer (9116).  It is stored internally as a 32-bit  
integer whose value (viewed as a decimal number) is in the format of yymmdd 
(year, month, day).
