Hello Guys,

Why it is showing as unsynchronized? Could you please recommend me any free NTP server? Thx.

I have also tried with :

0.ch.pool.ntp.org

Never use a Windows device as an NTP source. Microsoft's implementation of NTP is not of the IEEE standard.

If you want an outside NTP source, make sure your firewall allows you to. Worldwide NTP pools can be found HERE.
