Even google isn't quite sure about the summer time. Not sure if that is just a Google German thing...

A few weeks ago I tried to find out what the current time in CET is. Asking google for "CET" gave me: "23:27 CET". Asking google for "CET time" (I know that "time" is twice in this case) gave me "00:27 CET".

The last one is wrong and should be CEST or even more correct would be just the same result for CET as I asked for

I am always forgetting the polarity. Seeing the cut-overs listed helps me:

    $ zdump -v Europe/Berlin | grep 2021
    Europe/Berlin  Sun Mar 28 00:59:59 2021 UT = Sun Mar 28 01:59:59 2021 CET isdst=0 gmtoff=3600
    Europe/Berlin  Sun Mar 28 01:00:00 2021 UT = Sun Mar 28 03:00:00 2021 CEST isdst=1 gmtoff=7200
    Europe/Berlin  Sun Oct 31 00:59:59 2021 UT = Sun Oct 31 02:59:59 2021 CEST isdst=1 gmtoff=7200
    Europe/Berlin  Sun Oct 31 01:00:00 2021 UT = Sun Oct 31 02:00:00 2021 CET isdst=0 gmtoff=3600

In this case, Google is providing a wrong answer to not confuse people. People don't understand that a time zone can exist but not be observed at the same time
