Hello Pierre-Yves,

  The  ntpd  from  OBSD  is  raw  and lame yet. It takes days (!) to really

synchronize, adjusting time and clock frequency back and forth (even if you

start  with  -s) so it's too early to say that using it is "right". It will

be "right" after it matures, gets more useful synchronization algorithm and

it's own ntpdate (or a parameter to synchronize and exit).
