I have set get time from internet in the indicator datetime.
timedatectl says:
$ timedatectl
Local time: Tue 2016-04-12 10:54:21 BST
Universal time: Tue 2016-04-12 09:54:21 UTC
RTC time: Tue 2016-04-12 10:54:20
Time zone: Europe/London (BST, +0100)
Network time on: yes
NTP synchronized: no
RTC in local TZ: yes
Warning: The system is configured to read the RTC time in the local time zone.
This mode can not be fully supported. It will create various problems
with time zone changes and daylight saving time adjustments. The RTC
time is never updated, it relies on external facilities to maintain it.
If at all possible, use RTC in UTC by calling
'timedatectl set-local-rtc 0'.
Which is consistent, but I'm not sure if that's right. My /etc/adjtime
says LOCAL, and I do have WIndows 10 installed. I should check if
WIndows 10 can handle UTC hardware clock.
The journal has many errors about failing to call adjtime.

Title:
[regression]: Failed to call clock_adjtime(): Invalid argument
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Xenial:
Confirmed
Bug description:
Steps to reproduce:
1) Force a time delta
date -s "now - 1 hour"
2) Restart systemd-timesyncd to have it fix the time
systemctl restart systemd-timesyncd
Expected behavior:
The clock should be back in sync.
Actual (problematic) behavior:
The clock stays out of sync because the call to clock_adjtime()
failed.

This problem doesn't happen when running kernel 4.4.0-16.32. Looking at the
changelog of 4.4.0-17.33 it could be because of the new feature introduced in
