      option-code   OPTION_ELAPSED_TIME (8). 

      option-len    2. 

      elapsed-time  The amount of time since the client began its
                    current DHCP transaction.  This time is expressed in
                    hundredths of a second (10^-2 seconds). 

   A client MUST include an Elapsed Time option in messages to indicate
   how long the client has been trying to complete a DHCP message
   exchange.
