Public bug reported:

Binary package hint: gnome-system-tools

In the Time and Date configuration window (documented on
<https://help.ubuntu.com/community/UbuntuTime>), the servers suggested
in the Time server window is inadequate.

Many of the servers suggested are stratum 1 servers (for servers around
Switzerland for instance I found out ntps1-0.cs.tu-berlin.de, ntps1-1.cs
.tu-berlin.de, ntps1-2.uni-erlangen.de, canon.inria.fr, chronos.cru.fr,
ntp.cesnet.cz, time.ien.it, ntp0.nl.net and ntp1.nl.net to be stratum
1).

Stratum 1 servers are servers directly connected to a reference clock.
Stratum 1 time servers should be used only by stratum 2 time servers
(serving a large number of clients and / or stratum 3 servers). Stratum
1 servers should not be used by terminal clients (see
<http://support.ntp.org/bin/view/Servers/RulesOfEngagement>) and should
not be advertised in the server selection window. Failing to do so will
increase stratum 1 servers load and consequently reduce their
availability, reducing the accuracy of the whole system.

Stratum 1 servers should be detected, removed from this selection
window, and replaced by stratum 2 (or even 3) servers which are good
enough for most cases. Ideally the NTP pool should be used (see bug
#104525).
