             Summary: Clock skew managment
                 Key: IGNITE-18977
                 URL: https://issues.apache.org/jira/browse/IGNITE-18977
             Project: Ignite
          Issue Type: Epic

*Motivation*
In a distributed system, all nodes have their own time view. A task to take current time on a particular node have no guarantee that the timestamp is achieved in all members in the topology. But our distributed algorithms required to time synchronization until a specific accuracy.
The time interval on which all cluster clock can different is called a clock skew. Cluster should support whatever any cluster node has the clock skew does not bigger that it is defined for the topology.
