Hi Massimo,

i've seen, but it do not document in details

Section IV states:

1)  From the command line and accessing a single server using command line
arguments:

os2_ntpd.exe [ntp server(name or dotted decimal)
               initial polling interval (integer seconds)
               number of requests to send (integer)]

How much more detail did you expect?

anyway
os2_ntpd 193.204.114.232 2 2

That's compatible with what the docs say.

ntp server RFC 5905, hour and date is right

You are looking at the wrong RFC

   5905 Network Time Protocol Version 4: Protocol and Algorithms

As I mentioned, OS2_NTPD impliements

   1305 Network Time Protocol (Version 3) Specification,

While both use the same NTP server data, the protocols are quite
different.
