DS3231 shield from Az-Delivery not working correctly

[gschmid_wac]

hello,
I tried for hours several sketches from here and from the RTCLib with Serial.print output, but all show the same effect:

rtc.adjust(DateTime(2022,9,28,20,01,30));
results in:

Day of the week: Monday
01:00:00
03/28/2009
Temperature: 17.00 C

and using compile time
rtc.adjust(DateTime((DATE), (TIME)));
results in:

Day of the week: Monday
16:00:00
03/28/2009
Temperature: 17.00 C

Also time and temperature do not change.

My opinion is: dead / damaged shield.
What do you think ?

Please post an example sketch that shows the problem and a schematic of your project

My opinion is: dead / damaged shield.

Are you sure the battery is good and inserted properly?

thanks for your replay,
battery is ok, but it doesnt matter, whether inserted or not.
The device must be partly damaged, for it responds/reads out values,
but does not accept the adjust values OR does not send correct data.
Perhaps there is an oscillator problem too, while time does not change ( e.g. seconds )

I better will order another one ...
