It wouldn't affect the time in which the policy was refreshed. Member servers and clients are updated every 90 minutes with an offset of +/- 30 minutes, and DCs are every five minutes. Did you restart the member server? Sometimes computer settings require a reboot, so the automatic refresh or gpudate can't make them take affect.
