            <title>[SERVER-46200] Implement a VectorClockService </title>
                <link>https://jira.mongodb.org/browse/SERVER-46200</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This task is to implement a &lt;tt&gt;VectorClockService&lt;/tt&gt;, which will unify, track, gossip and ensure persistence for all of the global vector clock components. Specifically, the components which it will track are: clusterTime, configOpTime, topologyOpTime.&lt;/p&gt;

&lt;p&gt;The VectorClockService will be hooked at all inbound/outbound network places in order to be able to gossip the global vector clock and should implement the following methods:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;gossipInMemoryVectorClockOut(BSONObjBuilder* outMessage)&lt;/li&gt;
	&lt;li&gt;gossipInMemoryVectorClockIn(const BSONObj&amp;amp; inMessage)&lt;/li&gt;
	&lt;li&gt;advanceVectorClock()&lt;/li&gt;
	&lt;li&gt;waitForInMemoryVectorTimeToBePersisted()&lt;/li&gt;
	&lt;li&gt;registerVectorClockChangeListener(ListenerInterface&amp;amp;  nonBlockingListener)&lt;/li&gt;
&lt;/ul&gt;
