Convert timestamp from API into date and add +3 hours

I have the following timestamps from an API call:

2022-05-22T13:53:42.010238Z
2022-05-22T11:53:30.910039Z
2022-05-22T11:46:43.904101Z
2022-05-22T11:46:27.815341Z
2022-05-22T11:46:12.581602Z
2022-05-22T11:41:56.246782Z
2022-05-22T11:41:39.443423Z

I would like to convert them into readable dates example: 22/05/2022-13:53:42 and also add +3 hours to them.

>Solution :

You can try below formula-

=SUM(SPLIT(SUBSTITUTE(A1,"Z",""),"T"))+TIME(3,0,0)
