We found that the synchronization time is incorrect today. After the synchronization time, we can see that the windows system only synchronizes the time once a week by default, and the frequency is too low. I searched for the information and found two ways to adjust the win7 time synchronization frequency.

 

Method 1: Registry

This method achieves synchronization by modifying the key value in the registry.

Registry Key value:

HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\W32Time\\

TimeProviders\NtpClient

Modify the following two key values:

SpecialpollintervalChange from 604800 to 86400.

This key value indicates the time interval in seconds. The original 7 days is 7*24*3600 = 604800 seconds.

A day is 24*3600 = 86400 seconds.

Create a DWORD Value named"Specialinterval", The value is 1

Step 2: restart the Windows times service.

Check whether the settings are valid:

 

Method 2: Scheduler

In Windows, there is a w32tm.exe, through which a parameter can be synchronized:

W32tm/Resync

 

Check:

Therefore, you can create a scheduled task and execute it once every day.
