Pc clock not updating vista

There is a Special Poll Interval setting under HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\services\W32Time\Time Providers\Ntp Client (note: it has moved at least once between Windows versions) which is the time (in minutes) between time syncs... While modifying that registry value may update the "next sync time" displayed in the control panel, I have found it does not actually affect how often the clock is synched.Feel free to play with it if you want but that's my verdict.

Note: The following process requires administrator (installation) rights on your computer.

The default time period is 7 days calculated in seconds.

On the other hand, my method (below) is a similar amount of effort and is trivial to verify: You can mess up your system time and then manually run the task to verify that it gets corrected right away.

The W32tool, with /resync argument, triggers a clock sync, provided the Windows Time service is running.

The following is an excerpt from 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.

Upon investigation, that task simply makes sure the Windows Time service is running and if it's already running the task does nothing.

In that situation it's still up to the Windows Time service when to actually performs a sync, which will be once per week.

Despite the apparent awfulness of PC clocks, Windows doesn't provide any user-facing options to change the clock-sync frequency below once a week.

I've seen suggestions that you change the existing Synchronize Time scheduled task so that it runs more often. I tried making that task run once a day and my clocks still drifted.

Change Your Firewall Settings Third party firewalls will often block the time servers, causing the sync to not work properly.
