Album export and HEIC format - question of understanding

Dear community,

For a long time I have been using a script that has been discussed several times here (e.g. https://discussions.apple.com/thread/7891804)...

I was able to copy photos with their albums into a file structure easily.

Because most photos were edited on my iPhone, I used the option "export edited version" of the script.

If I export the photos saved as HEIC now, the photo is saved as jpeg and is given the creation date "today" due to the conversion.

Is it possible to export the "edited version" with the script while keeping the recording date and format (HEIC)?

Thank you for your help.

Many greetings

Tom
