ecours' system clock is wrong

Originally created by @intrigeri on #13518 (Redmine)

Reported a month ago (https://gitlab.tails.boum.org/tails/sysadmin/-/issues/11557#note_53296) and it’s still wrong:

$ date --utc
Wed Jul 26 08:16:05 UTC 2017
$ ssh lizard.tails.boum.org date --utc
Wed Jul 26 08:16:05 UTC 2017
$ ssh ecours.tails.boum.org date --utc
Wed Jul 26 09:46:07 UTC 2017

This makes it really painful to debug problems raised by our monitoring system: one has to find out what offset to apply to the date/time seen on the Icinga2 dashboard before one can correlate it with other system events & logs.

In ecours’ Journal I see a lot of:

systemd-timesyncd[19757]: Timed out waiting for reply from 66.228.54.198:123 (0.debian.pool.ntp.org).
