How to Use "Internet Time" Synchronization in Windows
InformationYou can synchronize your computer clock with a internet time server. This means that the clock on your computer is updated to match the clock on the time server, which can help ensure that the clock on your computer is accurate. Your clock is typically updated once a week and needs to be connected to the Internet for the synchronization to occur.
This will show you how to synchronize your PC time with the internet time, and how to troubleshoot and solve problems while doing it in Vista, Windows 7, and Windows 8.

WarningTO HELP PREVENT TIME SYNCHRONIZATION PROBLEMS
- Make sure that the time zone and date and time are manually set correctly on your computer, or you may have a hard time trying to synchronize your computer clock with a internet time server. If the time is to far off, it may not be able to synch with the time server.
- Windows gets the initial time from the BIOS, so check to see if the time and date are correct in the CMOS settings in the BIOS.
- Check the CMOS battery on your motherboard to see if it is getting weak and dying. If weak, it can cause your clock to run slow, loose time, or reset if dead. If this is the case, you will just need to replace the battery. It will usually be a lithium button cell, type CR2032. Check your motherboard documenation to be sure.
- If your computer will not keep accurate time even after synchronizing and changing the time servers below, then see How to Change the Internet Time Synchronization Update Interval in Windows.
- If you have a 3rd party firewall program installed or router, then check their settings to make sure that they are not set to block the NPT access on UDP port 123. It should be set to open or allow. Windows Firewall will allow Internet Time Server through by default, unless changed.
NoteThe Internet Time Synchronization uses the Windows Time Service with the default settings of Started and Automatic.
