HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config
说明：

Note that while a system does not request samples more frequently than this,a provider can produce samples at times other than the scheduled interval. The default value for domain controllers is 6. The default value for domain members is 10. The default value for stand-alone clients and servers is 10.
