Kubuntu + Wifi = Time + 1 hour

Question

Time Management

The problem is approximately the following. There is a new laptop "Samsung 700z5-s01".
It has a week old Kubuntu on it.

Every time you connect to WiFi (just turn it off and on), the time goes off by +1 from the present. (not +1 hour each time, but only if the time is correct).

In "System Settings - Date and Time" the time zone is correct, setting the time via ntp is disabled.

I tried to change the time both through the GUI and through " kdesudo systemsettings" and through " sudo date 011815512012.50", the result is always the same - it's worth reconnecting, as the time goes astray.

Answer 1

Are you from Ukraine? Due to Rada's games with time zones, not all time sources understood and correctly set what time zone we have.
Try to put just a deliberately wrong belt and / or location with the calculation of the adjustment.
Why disabling ntp does not help - I do not know.
