How to increase frequency of time server synchronizations?

I have a that PC (Windows XP SP3) keeps losing time whereby it ends up being about 5 mins slow per day from all the other PCs and clocks about the place.

Is there a way to increase frequency of time server synchronisations to keep this in check? Or better yet, a reason for this issue, perhaps some recent windows update has this side effect I wouldn't know.

You can adjust it in Registry.

  • start registry editor (regedit will do fine)
  • go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient
  • edit value SpecialPollInterval.

SpecialPollInterval is defined in seconds. If you wish e.g. 1 hour just write 3600. You can calculate rest from here. Default is 604800 (7 days).

2Yep that'll do it! Didn't seem to take effect until I changed the provider, but good enough. Thanks. – Scott Bennett-McLeish – 2010-04-30T11:27:41.310

It's recommended to not set this property below 14400 (4 hours) to avoid getting banned from the time servers. – None – 2011-05-13T06:57:00.183
