I suggest 1:15am as it's 15 minutes after the default Synchronize Time task. Set the task to run daily at the time you want. Set it to run with highest privileges and to be configured for your OS version. Set the new task to run as the LOCAL SERVICE user. (You can create the task anywhere but you might as well keep things tidy.)

įind the Microsoft / Windows / Time Synchronization branch and click Create Task.

Open Task Scheduler (on Vista and above, just type that into the Start Menu and you'll find it). It's easy to set up a scheduled task which ensures the Windows Time service is available and then runs W32tm.exe /resync once a day, or as often as you like: (If you want to test it manually, note that the command requires administrator rights and that the service may need to be started.) The W32tm.exe tool, with /resync argument, triggers a clock sync, provided the Windows Time service is running. 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. I suspect if you modify the SpecialPollInterval value and change the Synchronize Time task frequency then it might work, but that is difficult to verify. After that the time service will not do anything - or run at all - until the Task Scheduler starts it again. When the time service runs is controlled by the Windows Task Scheduler, not the registry value, and (at least on Windows 7) when the service runs it exits immediately after performing any required work. Feel free to play with it if you want but that's my verdict.Īs far as I can tell, the registry value changes how often the time service wants to sync but only applies when time service is actually running.

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.

There is a SpecialPollInterval setting under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\TimeProviders\NtpClient (note: it has moved at least once between Windows versions) which is the time (in minutes) between time syncs. How not to do it 2: The SpecialPollInterval registry value In that situation it's still up to the Windows Time service when to actually performs a sync, which will be once per week. Upon investigation, that task simply makes sure the Windows Time service is running and if it's already running the task does nothing. I tried making that task run once a day and my clocks still drifted.

I've seen suggestions that you change the existing Synchronize Time scheduled task so that it runs more often. How not to do it 1: The Synchronize Time task

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. They seem to drift by about five minutes each week and that messes up things like scheduled TV recordings or stating that it is 13:37 o'clock on IRC when it's not.

I don't know about your machines but both my desktop and my HTPC have terrible clocks.

This was tested on Windows 7 but should work with Windows XP and above.

This page explains how to make the Windows network time (NTP) client synchronize its time more often than the default once per week.
