| //The master answers with message type 2 and his time hex encoded. The next five steps were originally designed to calculate the time offset between master and slave to determine the correct time slots. In the current implementation this is not needed because clients are NTP synced. Normally the client would answer by adding his time. As a dummy "0000" is used here.// | //The master answers with message type 2 and his time hex encoded.
