此前写了篇《
但如果windows系统不能上公网时，必须使用本地的时间服务器。由于我linux局域网的时间服务器地址是192.168.12.31.如果直接将时间服务器的IP修改为192.168.12.31, 更新时间会失败。加入域的windows缺省的时间同步类型是nt5ds，没有加入域的是ntp.
可以在windows直接安装一个ntp时间服务器。比如到此下载 ：http://www.meinberg.de/english/sw/ntp.htm
现在既然linux已经有了时间服务器，就不必再安装时间服务器了。
由于windows自带时间同步客户端，可以直接修改注册表配置。
方便起见，直接导入注册表文件。

将以上脚本另存为ntp.reg, 192.168.12.31修改为你要的ntp服务器地址，然后导入。
Windows ntp客户端配置
除标准时钟服务器外，其它的Windows 平台都作为客户端，不需要安装程序，只作注册表配置。导入压缩包里的注册表ntp.reg ，打开注册表，根据需要做以下修改：
1 ．如果导入前没有修改ntp地址，则必须进入注册表编辑如下键值
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/W32Time/Parameters/NtpServer
这一项是设置标准时钟源IP 地址的。将192.168.12.31 替换为选定的时钟服务器的IP 地址，后面的,0x1 留着不要改。
2 ．(根据需要更改)
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/W32Time/TimeProviders/NtpClient/SpecialPollInterval
这一项是设置客户端向服务器同步的轮询间隔，单位为秒，默认设为1 小时，可根据需要做修改。
3 ．( 根据需要更改 )
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/W32Time/Config/MaxPosPhaseCorrection
这一项是设置最大的正时间校准量，单位为秒，默认设为15 小时，可根据需要修改。
4 ．( 根据需要更改)
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/W32Time/Config/MaxNegPhaseCorrection
这一项是设置最大的负时间校准量，单位为秒，默认设为15 小时，可根据需要修改。
5 ． 退出注册表编辑器。
6 ．在命令提示符处，键入以下命令以重新启动 Windows 时间服务，然后按 Enter ：
net stop w32time && net start w32time
也可以到系统的服务里找到windows time服务，重启该服务。对集群服务器，会引起集群服务的关闭。
