[ntp:questions] sntp does not set the system time/date

Hi,

After building and installing ntp 4.2.6p2 on both SLES 10, and on SLES
11 SP1, it seems that sntp does not ever set the time/date successfully.
It doesn't seem to matter if I use -j or -s.

Before testing sntp, I set the time to only a couple of minutes
"behind". 

This is the output I get, but it never sets the date:
(running as root)

# sntp -d -s
