To format an arbitrary timestamp you want "+%Y-%m-%dT%H:%M:%S.%1NZ", 
unless you always want a zero after the period.


Closing the bug report as there's no bug here.

Hi Andreas,

thank you for your help, I didn't realize I was using the wrong format for
what I wanted.
I don't have much experience with the project.
The format I wanted was: -MM-DDThh:mm:ss.sZ
is +'%Y-%m-%dT%H:%M:%S.0Z' do what I want or are there still some mistakes
there?

Thank you again and sorry for the bug report, it was late and I was sure to
have found a bug ^^"

Best regards

Stéphane Archer

It doesn't make sense to use %G without %V, or to use it in place of %Y.

$ date -d "17 april 2022 + 37 week 5pm" +'%G/%V %Y-%m-%dT%H:%M:%S.0Z'

Hi,
I hope this is the right place to do my bug report.
please see the following shell input-output:
```
$ date -d "17 april 2022 + 36 week 5pm" +'%G-%m-%dT%H:%M:%S.0Z'
2022-12-25T17:00:00.0Z
$ date -d "17 april 2022 + 37 week 5pm" +'%G-%m-%dT%H:%M:%S.0Z'
2022-01-01T17:00:00.0Z
$ date -d "17 april 2022 + 38 week 5pm" +'%G-%m-%dT%H:%M:%S.0Z'
2023-01-08T17:00:00.0Z
```
as you can see the input "17 april 2022 + 37 week 5pm" makes date return
the wrong output for some unknown reason.

Do I do something wrong?
I use the following version: date (GNU coreutils) 8.30
