+as GPS receivers, or even manual input of the correct time from a wristwatch.
+
+Chrony will determine the rate at which the computer gains or loses time, and
+compensate for it.  It can also operate as an NTPv4 (RFC 5905) server and peer
+to tell time to other computers on the network.
+
+It's designed to perform well even under adverse conditions: congested
+networks, unreliable clocks drifting with changes in temperature, and devices
+or virtual machines that are frequently turned off and connect to the Internet
+for only a few minutes at a time.
+
+Typical accuracy when synchronised over the Internet is several milliseconds.
+On a local network this can reach tens of microseconds.  With hardware
+time-stamping or reference clock, sub-microsecond accuracy is possible.")
