The string is this one:

2024-05-08T09:55:57Z

And with this:

content?matches('[0-9]{4}-[01][0-9]-[0-3][0-9]T[0-2][0-9]:[0-5][0-9]:[0-5][0-9]([+-][0-2][0-9]:[0-5][0-9]d|Z)')

content?datetime?string['dd.MM.yyyy, HH:mm']

I have:

Unparseable date: "2024-05-08T09:52:55Z"

I can’t understand what I am doing wrong.
