Windows 10

To get started, click the “Start” box at the bottom left of your desktop

Type “gpedit.msc” and select “gpedit”

When the command is executed, a window called “Local Group Policy Editor” will open

Go to the “Computer Configuration” section, then “Administrative Templates”

Next, go to the “System” section

Next, the “Windows Time Service” section

Then go to “Time Providers”

On the right, select the “Enable Windows NTP client” setting

Double-click the left mouse button, the settings window will open

Switch to “Enabled” mode and press the “OK” button

Go to the “Configure Windows NTP client” setting

In the settings window, switch the mode to “Enabled”

We change the items, in the “NtpServer” field we specify the IP address of the NTP server or its DNS name, for example “pool1.ntp.od.ua”, or any other server from our list, and through which a special server flag is specified, in in this case it is “0x9”

In the “Type” field, indicate that we will use the “NTP” protocol

In the “SpecialPollInterval” field, we specify “900” seconds, this is the server polling interval

Save by pressing the “OK” button

Close the “Local Group Policy Editor” window

The next stage is setting up the time synchronization service

Click in the “Search” field

Enter the “services.msc” command, and select “services” from the resulting list

The “Services” window will open, select “Windows Time Service” from the list

Select the service, press the right mouse button and select “Properties”

The settings window will open

Change “Startup type” to “Automatic” mode

Then start the service by clicking the “Start” button

Save the changes by pressing the “OK” button

Close the “Services” window

open search, write “cmd”

run on behalf of the administrator

the console will open, enter the command

sc triggerinfo w32time start/networkon stop/networkoff

execution result

The next step is to monitor the operation of the service by viewing and analyzing the logs

Click on the “Search” field in the lower left corner of the desktop

Enter the “eventvwr.msc” command and select “View event logs” from the list

The “Event Viewer” window will open, select the “Windows Logs” item in the left part

Select the “System” magazine

We find the event whose source is “Time-Service”

Double-click on the event with the left mouse button, a detailed description window will open

In this case, the log event of a successful synchronization with an external NTP server

Close the “View events” window

Now let’s check how much time our clock works

Click in the “Search” field

Write the “cmd” command

A “Command Prompt” window will open.

Enter the command “w32tm /stripchart /computer:pool1.ntp.od.ua /samples:3”

Where “w32tm” is a time service management tool, “stripchart” displays a graph with statistics of clock deviations, “computer:pool1.ntp.od.ua” is a remote NTP server with which we compare the local clock, and finally the argument “samples:3” means to build graph of only 3 connections

An example of program execution

This graph shows that at 2:41:31 the first of three test connections was made to an external NTP server, the result showed a response delay from the server of +00.0112548 seconds and a time difference of +00.0029020 seconds

The setup is complete, the test showed acceptable results and confirmed the functionality of the time synchronization service in Windows 10.
