Every now and then, usually some time at night the system time in Ubuntu 16.04 changes to Los Angeles time. I live in the UK and it is normally set to London. My HP Pavilion DV6 laptop did not restart during this time. Is there a way to find out what causes this and how to correct? It's not a dual boot setup, so it can't be Windows.

Check current timezone settings by opening a terminal and executing : timedatectl status
$ timedatectl status Local time: Di 2017-03-21 14:32:44 CET Universal time: Di 2017-03-21 13:32:44 UTC RTC time: Di 2017-03-21 13:32:44 Time zone: Europe/Berlin (CET, +0100) Network time on: yes
NTP synchronized: yes RTC in local TZ: no Important is that RTC in local TZ is set to no - change the timezone settings by executing :
timedatectl set-local-rtc 0
timedatectl set-ntp true
timedatectl set-timezone Europe/London Make sure that Network time on and NTP synchronized are set to yes - reboot the system.
Enter the BIOS ... check (modify in case they are wrong) time settings there - then boot Ubuntu.
Check whether the time synchronization service is running with : systemctl status systemd-timesyncd.service. For reference and more comprehensive information -> man timedatectl
