How to synchronise system clock with NTP in Windows 11

1. Open Date & Time Settings
   1. Right-click the clock in the bottom-right corner of the taskbar and select Adjust date and time (or press Win + I and navigate to Time & language > Date & time).
2. Verify Automatic Time Settings
   1. Ensure Set time automatically is switched to On.
   2. Confirm your Time zone is set to your correct broadcast region.
3. Force Immediate Time Synchronisation
   1. Scroll down to the Additional settings section.
   2. Click Sync now. A tick mark and the exact timestamp of the last successful sync will appear.

If you don’t see this option or get a synchronization error, then you can use this method which will force synchronization with the public NTP pool:

1. Configure & Resync via Terminal / PowerShell
   1. Press Win + X and select Terminal (Admin) (or search for PowerShell, right-click, and select Run as administrator), then run:
   2. 
net stop w32time; w32tm /config /manualpeerlist:"0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org 3.pool.ntp.org" /syncfromflags:manual /reliable:YES /update; net start w32time; Start-Sleep 2; w32tm /resync /force


Broadcast Drift Verification:-

In the terminal, run w32tm /query /status. Check the Phase Offset line to confirm your machine is within ±0.3000000s (300 ms) of the NTP reference clock.
