kubuntu 18.04
KDE plasma 5.12.7

my timezone changed from summer time to standard time recently. Ever since all the clock widgets are wrong - digital clock is 2 hours behind. Analogue clock and fuzzy clock are 2 hours ahead.

Date & time in system settings shows the right time and is set to use automatic date and time. Timezone is set to my current time zone. Running 'date' in command line shows the correct time and timezone

Digital clock widget has an option to configure timezone. Setting to my system time and and my actual timezone doesn't fix it.

Analogue clock and fuzzy clock have no time or timezone configuration so I presume they are meant to be tied to the system time.

Can't reproduce this here, using Kubuntu 18.10 with Plasma 5.14.3, so I guess this is probably already fixed since a while.
