time.fu-berlin.de is not an ntp server, so that's a different problem
than rdate.

I seem to recall that rdate isn't very good at giving error
information.  Are the two systems configured identically?  A raised
securelevel(8) (level 2 or higher) will keep the time from getting
changed by more than 1 second...
