How to Change the Interval for Updating the Computer's Clock

By default, XP updates the computer's clock by synchronizing with an Internet time server at one hour intervals. If you'd like Windows to synch the time more or less frequently, you can change the interval by editing the registry. Here's how:

  1. Open your favorite registry editor.
  2. Navigate to the following key in the left pane: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\W32Time\TimeProviders\NtpClient.
  3. In the right pane, double click the entry called SpecialPollInterval.
  4. In the Base section of the Edit DWord Value dialog box, click the Decimal option button.
  5. Enter the desired interval in seconds (3600 = 1 hour, 1800 = 30 minutes, 86400 = 24 hours, and so forth).
  6. Click OK and close the registry editor.
