Procedure and query execution statistics for natively compiled stored procedures record worker time in multiples of 1000
Issue: After you enable the collection of procedure or query execution statistics collection for natively compiled stored procedures using sp_xtp_control_proc_exec_stats or sp_xtp_control_query_exec_stats, you see the *_worker_time reported in multiples of 1000, in the DMVs sys.dm_exec_procedure_stats and sys.dm_exec_query_stats. Query executions that have a worker time of less than 500 microseconds will be reported as having a worker_time of 0.
The issue was first fixed in the following cumulative update of SQL Server.
