changes time

Strange, I'll check my netbook later.

Linux Mint in dual boot or as Live ?

Dual boot.

Tested at my dualboot netbook (mint & win10), both systems hold the same time as RTC. Can you copy output of timedatectl command here? It should look similar to this:


If you change time in Windows, do not set it manually but use Sync Now option in Control Panel. (Sometimes it is necessary to click on it twice.) And in Settings app, Automatic selection of timezone should be Disabled.


(Unfortunately, there is no simple way to install English language pack in Home edition; sorry for different language.)

And if all else fails: you can use 3rd party timesync program, for example
Thinking Man Software - Dimension 4 v5.3

Welcome to fish, the friendly interactive shell
allan@AllansLaptop ~> timedatectl
Local time: Thu 2018-05-31 20:52:03 PDT
Universal time: Fri 2018-06-01 03:52:03 UTC
RTC time: Thu 2018-05-31 20:52:02
Time zone: America/Vancouver (PDT, -0700)
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'.

I'll try the Windows thing next time I'm in Windows.

AllanP: timedatectl output is ok, now try to force internet time sync twice in windows control panel. Do not set time manually.

Please check & set timezone settings according to pictures (except TZ value, should be UTC-8 instead of UTC+1). Then click on Update Now button three times.

Also avoid external timesync programs (AtomicSync for example). Furthermore, check the RealTimeIsUniversal value in registry - it should be either 0 or missing.
