Are you sure that your /etc/ntp.conf ist correct?

# cat /etc/ntp.conf

server time.fu-berlin.de iburst maxpoll 9

You must add "restrict" lines for every server and for
localhost, like these:

restrict time.fu-berlin.de nomodify
restrict 127.0.0.1

Why?

That really makes no sense to me whatsoever.

Other than that, the config looks good.  There's no need
to add further time servers.

The time adjustment algorithms of NTP make use of multiple time sources. NTP works best with having at least three reachable servers. Of course ntp is designed to keep good time even when you are disconnected from the net, but it builds up its data from multiple sources and using triangulation to correct for errors.
