-/**
- * this file provides the time synchronization extension to cometd.
- * Timesync allows the client and server to exchange time information on every 
- * handshake and connect message so that the client may calculate an approximate
- * offset from it's own clock epoch to that of the server.
- *
- * With each handshake or connect, the extension sends timestamps within the 
- * ext field like: {ext:{timesync:{tc:12345567890},...},...}
- * where ts is the timestamp in ms since 1970 of when the message was sent.
- *
- * A cometd server that supports timesync, should respond with and ext field
- * like: {ext:{timesync:{tc:12345567890,ts:1234567900,p:123},...},...}
- * where ts is the timestamp sent by the client, te is the timestamp on the server
- * of when the message was received and p is the poll duration in ms - ie the
- * time the server took before sending the response.
- *
- * On receipt of the response, the client is able to use current time to determine
- * the total trip time, from which p is subtracted to determine an approximate
- * two way network traversal time. The assumption is made that the network is
- * symmetric for traversal time, so the offset between the two clocks is 
- * ts-tc-(now-tc-p)/2. In practise networks (and the cometd client/server software)
- * is never perfectly symmetric, so accuracy is limited by the difference, which 
- * can be 10s of milliseconds.
- *
- * In order to smooth over any transient fluctuations, the extension keeps a sliding
- * average of the offsets received. By default this is over 10 messages, but this can
- * be changed with the dojox.cometd.timesync._window element.
