Summary:A method and system are disclosed for implementing a client of a distributed lock manager comprising a plurality of nodes. The client is configured to send a request to the distributed lock manager, the request including a local time of the client. The client receives a response to the request from a node of the distributed lock manager where the request includes an echo of the local time included in the request. The response also indicates that a lock corresponding to a given resource has been granted to the client and the client subsequently utilizes the resource. The client subsequently determines that a safe period of time has elapsed for using the resource. This determination is dependent at least on a client staleness corresponding to a difference between the echoed time and current local time at the client.
