It does not anything with ntpdate -v localhost | ntpdate localhost

but ntpdate -d localhost | ntpdate -q localhost do work indeed.

What probably compounded (my apparent confusion) is that tools ntpq |
ntpdc I commonly use to check upon ntpd are not working (as you explained).

Thank you for your effort/input.
