-   TimeSyncer allows us to synchronize time between a client and a server.
-   The client sends a UDP packet containing its send-time to the server,
-   the server sends that packet back to the client amended with information
-   about when it was received as well as the time the reply was sent back.
-   Finally the client receives the reply and has now enough information to
-   compute the clock offset between client and server assuming that packet
-   exchange is symmetric, i.e. time for a packet client->server and
-   server->client is roughly equal.
-   This exchange is repeated a number of times and the average offset computed
-   over the 30% of packets that had the lowest roundtrip times.
-   The offset is determined every 10 secs to account for slight differences in
-   clock frequency.
