腾讯云 windows ntp校时

代码是在≥2012R2的系统上powershell测试的，代码未在≤2008R2的系统上测试；仅供非域环境参考。

腾讯云windows镜像2021年上半年优化过一次，其中有ntp相关的一些参数优化

针对老机器时间误差的问题，解决方案如下：

以管理员身份运行

首先执行reg query命令查看当前配置

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\WOW6432Node\Policies\Microsoft\W32time\Parameters | findstr "NtpServer Type"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config | findstr "PollInterval"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

组策略NTP客户端配置里的Type要着重注意下

计算机配置 → 管理模板 → 系统 → Windows时间服务 → 时间提供程序 → 配置Windows NTP 客户端

NTP同步出错的问题，注意检查下这里是不是NTP类型，如果不是改成NTP类型，并重启windows time服务

公共镜像这里是NTP。

部分2008R2老机器如下图

然后执行下面命令优化（每隔1分钟校时一次）

net stop w32time 2>&1 > $null

#w32tm /unregister

#w32tm /register

sc.exe triggerinfo w32time delete ; sc.exe config w32time start= auto

sc.exe triggerinfo w32time start/networkon stop/networkoff

net start w32time

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config" /v "MinPollInterval" /t reg_DWORD /d 5 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config" /v "MaxPollInterval" /t reg_DWORD /d 10 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 60 /f

reg add "HKLM\SOFTWARE\Policies\Microsoft\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 60 /f

reg add "HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 60 /f

w32tm /config /update

w32tm /config /manualpeerlist:"time1.tencentyun.com,0x8 time2.tencentyun.com,0xa time3.tencentyun.com,0xa time4.tencentyun.com,0xa time5.tencentyun.com,0xa" /syncfromflags:manual /reliable:yes /update

net stop w32time

net start w32time

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\WOW6432Node\Policies\Microsoft\W32time\Parameters | findstr "NtpServer Type"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config | findstr "PollInterval"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

w32tm /resync

start-sleep 3

w32tm /resync

start-sleep 3

w32tm /resync

SpecialPollInterval ∈ 【2^MinPollInterval,2^MaxPollInterval】

腾讯云平台目前的默认值是300 ∈ 【2^6,2^10】，我调成60 ∈ 【2^5,2^10】了，1分钟校时1次，过去的太乱了我半年前做了一次统计现在找不到了，印象中有3600（1小时），有604800（7天），乱得很，现在是300秒，阿里云也是300秒。

每5分钟校时一次的话命令如下

net stop w32time 2>&1 > $null

#w32tm /unregister

#w32tm /register

sc.exe triggerinfo w32time delete ; sc.exe config w32time start= auto

#sc.exe config w32time start= delayed-auto

sc.exe triggerinfo w32time start/networkon stop/networkoff

net start w32time

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config" /v "MinPollInterval" /t reg_DWORD /d 6 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config" /v "MaxPollInterval" /t reg_DWORD /d 10 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 300 /f

reg add "HKLM\SOFTWARE\Policies\Microsoft\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 300 /f

reg add "HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\W32Time\TimeProviders\NtpClient" /v "SpecialPollInterval" /t reg_DWORD /d 300 /f

w32tm /config /update

w32tm /config /manualpeerlist:"time1.tencentyun.com,0x8 time2.tencentyun.com,0xa time3.tencentyun.com,0xa time4.tencentyun.com,0xa time5.tencentyun.com,0xa" /syncfromflags:manual /reliable:yes /update

net stop w32time 2>&1 > $null

net start w32time

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\Parameters | findstr "NtpServer Type"

reg query HKLM\SOFTWARE\WOW6432Node\Policies\Microsoft\W32time\Parameters | findstr "NtpServer Type"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config | findstr "PollInterval"

reg query HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

reg query HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\W32Time\TimeProviders\NtpClient | findstr "PollInterval"

w32tm /resync

start-sleep 3

w32tm /resync

start-sleep 3

w32tm /resync

如果时间偏差超过15小时（54000秒）可能会无法自动校时，解决方案参考：https://cloud.tencent.com/developer/article/1920090
