Cannot sign in to Lync because your computer clock is not set correctly - Lync 2013

Hi,

I have this error "Cannot sign in to Lync because your computer clock is not set correctly" when I try to connect to a Lync Server 2013 test environment.

All my servers and client machines have the correct date and time. The servers and external client machines are in different time zone.

No error or warning events on event viewer.

Kerberos and NTLM is enabled.

Thanks,
