This removal comes to avoid some redundant requirements which are adding more problems on a production setup. Here are the list of checks for time as they happen - Fresh connect (during server startup) - CORRECT - A reconnect after network disconnect - CORRECT - For each RPC call - INCORRECT. Verifying time for each RPC aggravates a situation where a RPC call is rejected in a sequence of events due to enough load on a production setup. 3 second might not be enough time window for the call to be initiated and received by the server.
