just for your records.

What would be alternatives?

Zeitgleich mit Hilfe des Network Time Protocol (NTP)

Um eine genaue Uhrzeit im Datennetz zur Verfügung zu haben, betreibt das Rechenzentrum einen NTP Timeserver, der seine Zeit von mehreren lokalen Funkuhren bezieht. Die Funkuhren werden ihrerseits mit der Normzeituhr in Braunschweig synchronisiert. Die Daten des Servers sind:

    ntp.uni-regensburg.de
    ntp.ur.de

Dieser Server ist sowohl vom Campus als auch von außerhalb der Universität erreichbar. Sie können jedoch auch die NTP-Server der Physikalisch-Technischen Bundesanstalt (PTB), Braunschweig und Berlin verwenden.

    ptbtime1.ptb.de
    ptbtime2.ptb.de
    ptbtime3.ptb.de

i gonna test those and report back…

apt-get update;
apt-get install ntp;

vim /etc/ntp.conf

# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
server ntp.ur.de
server 0.debian.pool.ntp.org iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst
