Sometimes it’s the little chores that make Windows great. When I find these little gems I save them in my hard drive. Here’s one of my favorites which I found on How-To Geek (http://www.howtogeek.com/) a couple of years ago. The following is not my work and all credit goes to How-To Geek. Hope this helps.

Change the Default Update Interval
If your clock is constantly out of sync even though it says the sync was successful, the problem could be that your computer is losing time because of a system clock problem. A workaround in this instance is to change the NTP client to update more often.

Open regedit.exe through the start menu search box, and then find this registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\w32time\TimeProviders\NtpClient
Double-click on the key on the right-hand side for SpecialPollInterval


The default time period is 7 days calculated in seconds. If you wanted to change this to update every day, you would use 86400, or 60 seconds * 60 minutes * 24 hours * 1 day.

I wouldn’t recommend setting this to anything less than 4 hours worth, or your computer might get banned by the time servers.

Change Your Firewall Settings
I don’t have a screenshot for you here, but third party firewalls will often block the time servers, causing the sync to not work properly. If you are using McAfee or another firewall, you’ll need to use the configuration utility to unlock NPT access on UDP port 123.
