The NFS client will getattr/OPEN at the point where the application opens the file (close to open consistency) and actimeo will not change that behavior. The "nocto" mount option will disable that. If the client is copying an older version of the file, then the client is either not checking the file's modification time correctly or the NFS server is not telling the truth.
