Package net.time4j.clock

Class DaytimeClock

java.lang.Object
net.time4j.clock.AbstractClock
net.time4j.clock.NetTimeConnector<NetTimeConfiguration>
net.time4j.clock.DaytimeClock
All Implemented Interfaces:
TimeSource<Moment>
public class DaytimeClock extends NetTimeConnector<NetTimeConfiguration>

Represents a connection to a DAYTIME-server following the old norm RFC 867.

Note that the format of the server reply is not specified by the protocol. Furthermore, many internet time servers have stopped to support this old protocol. Actually in year 2014, at least the addresses "time.nist.gov" and "time.ien.it" are still working. Applications cannot expect more than second precision at best.

Note: This implementation is threadsafe.
