Windows time sync issue with BSNL FTTH and workaround

Noticed that the Windows 11 machine I was working on had 11:32 showing as the time when it was well into the afternoon. Found this thread,
https://broadbandforum.co/threads/cannot-sync-network-time-ntp-on-win10-on-bsnl-ftth.202104/

So apparently Windows tries to poll port 123 from port 123, and that is blocked by many ISPs. 

The easiest workaround was to install NetTime which probably changes the source port and gets around the block.
