Exported JPG has wrong date

[greggman]

I'd expect (like every other program I own) that when I export a file the date on the file in the filesystem is the date at the time I save the file. It's new file. It's creation date should be now. But apparently Affinity Photo sets the date as the the time the picture was taken (or maybe it's setting them to the time of the file opened). All I know is I exported a file, expected to see it at the top of the file list in Finder/Explorer like every other app including Photoshop but instead of being dated 2020-09-25 it was dated 2018-08-12  This makes it impossible to use the filesystem like it's been used for the last 40+ years where you can sort files by date and see the files you just created.

Steps to repo. 

1. Load a file (in my case an .HEIC file) with a date before today

2. Export as JPEG

3. Look at the date in the Finder/Windows Explorer

What should happen:

The date should be today

What happened instead

The date is some past date.

This must be a Mac issue. I've tried with several different formats on my Win 10 system, and the System Properties had the correct dates, AND it did not alter the correct actual creation date, ie; the date the photo was taken.

But it's posted in a Windows forum

Check you are looking at the Date Modified field not the Date Created field

If you do not see the Date Modified field you should be able to add it there

This answer is old (Windows 7), but I think it still applies even in Windows 10:
