I used the search function but there was just too much information with too many different methods. I just want to solve this problem, after 1 hour of searching.
I get a string like this from Firestore: 2018-05-22T10:30:00+00:00 (can change if needed)
Now I want to change the time to the local timezone on the device. At the end I need 2 different strings like these:
hour: 10:30 date: Tuesday, May 22
