Photo Creation Date not saved / iPhone "Moments" Album missing

I noticed that the uploaded photos do have a current creation date, not the creation date of the photo. Can I change this behavior ?

Is there a possibility to access the iPhone “Moments” Album, as this has year/month/day support?


The photos app has month/year support.

the photos app has.

I am asking in the context of the Nexcloud App, if it has access to the “Moments” Album, so that it can use the time do upload the photos on the server.
