      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.

      
   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.  The elapsed time is measured from the time at which the
   client sent the first message in the message exchange, and the
   elapsed-time field is set to 0 in the first message in the message
   exchange.

  (1*)PASS: NUT transmits Solicit message with Elapsed time option with elapsed-time field set to 0.
  (2*) - (6*)PASS: NUT transmits Solicit message with Elapsed time option with elapsed-time field set to the time elapsed since the first Solicit message was received (+0.5 or - 0.5 second).
