How to Change the Internet Time Synchronization Update Interval in Windows

information   Information
This tutorial will show you how to change the Internet Time Synchronization Update Interval to be updated more often in Vista, Windows 7, and Windows 8.

This could be used as a workaround if your system clock is constantly out of sync or slow, even though it says the sync was successful.

Note   Note

  • Windows gets the initial time from the BIOS, check to see if the time and date is correct in it if the time is always incorrect.
  • If the system clock loses track of the time when you shut down the computer, then this could be the CMOS battery on your motherboard getting weak and dying. You will just need to replace the battery. This is usually a lithium button cell, type CR2032.
  • A slow system clock while running is usually due to interference from some other program. This can sometimes be the antivirus or firewall program. You can test this by not running the suspect program for a few days to see if the time is accurate again. If it is the program, then you will either need to adjust it's settings to prevent the interference or find a different program to use instead that does not interfere.
  • For how to do Internet Time Synchronization after you finish this tutorial, see How to Use Internet Time Synchronization in Windows.
warning   Warning
Do not change the Interval to less than every 14400 seconds (4 hours), or your computer might get your computer's IP address banned by the time server.



FIRST:

1. Try changing the time server to another one that may Synchronize without any errors. See the Warning in the link below to.





Here's How:
1. Press the Windows+R keys to open the Run dialog, type regedit, and press Enter.​
2. If prompted by UAC, then click on Continue (Vista) or Yes (Windows 7/8).​
3. In regedit, navigate to the location below. (see screenshot below)​
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32Time\TimeProviders\NtpClient

4. In the right pane, right click on SpecialPollInterval and click on Modify. (see screenshot above)​
5. Select (dot) Decimal. (see screenshot below)​

6. Type in how often you want it to update the time in seconds, and click on OK. (see screenshot below)​
NOTE: The default time is every 604800 seconds (7 days). For every day, use 86400 seconds. (60 seconds X 60 minutes X 24 hours X 1 day)

Why would they band you if you update less than four hours i setup my computer to update every second that i am connected to the internet no problems, I have it setup since Dec 21, 2007.
 
Hi Matthew,

Welcome to Vista Forums. :party:

Anything under every 4 hours of checking with the time server, could put a strain on the time server if a lot of people did this. This is why there could be a chance that the time server would ban your IP address from being able to connect to the time server for updates. Anything under 4 hours is really just overkill. Usually every 24 to 12 hours is fine if you need to make sure your time is accurate each day.

With it set to every second to check with the time server, I would be surprised if you did not have higher CPU and Network usage.

Hope this helps,
Shawn
