Let Windows 7 time display be more accurate

Left click on the Windows 7 time bar, click on the "Delete date and time settings" in the pop-up window (red box below).

Next, switch to the "Internet Time" tab, click "Change Settings", in the pop-up server column, delete the default time.windows.com, and then enter a new server address :pool.ntp.org, click “Update Now” when done.

After the update, the last synchronization success time will be displayed. The automatic synchronization frequency of the server is one week. Compared with the Windows default time server, pool.ntp.org has applications on various systems/servers. Reliability is not a problem.

After the setting is completed, the accuracy of the Windows system time will be greatly guaranteed. Of course, you can also try to create a scheduled task and let it update once a day. This work is left to everyone to do it yourself.
