The iOS 14 Beta could be an issue.
Do you have backups?
If I understand you need to fix the date metadata (EXIF data) on your photos because of something that happened, the cause of which you are unsure of correct?
Are you referring to the File date or the Exif date?
How far off are the dates by? Is the date discrepancy visible on iOS beta or on the Mac, on both devices?
It's difficult to know how to answer the question without more info, which app and device are you seeing the date change issues on? What version of Photo.app are you using? Is all your software up-to-date? Were these photos taken by a camera, in which case the EXIF data should display the date the photograph was taken on or otherwise?
Could you come back with a few more details so that I can be more effective?
One thing you could try to isolate the source of the issue is to use a third party EXIF tool to inspect the EXIF data so that you can rule out whether the file metadata was damaged/skewed or if it is the app that is misinterpreting the information. So you could try this strategy to verify the findings as innate to the file or sourced from the app you are using to view the said EXIF data.
If have brew installed on your Mac you could search and install something fairly quickly. A great free tool is exiftool. Install it with brew, the enter exiftool in the terminal followed by a space and then drag and drop your photo in the terminal window and it will reveal all the metadata including EXIF data that you could ever dream of.
As a point here, exiftool actually has an option called
-globalTimeShift SHIFT Shift all formatted date/time values
As I write this is it possible that you might have used some utility against the images that cause a time shift. If not don't worry but consider if the surprise of seeing the time go off might not be related to some previous action on your part. Something to probe if true or not otherwise ignore this remark.
You can try confirming if the exif data is ok in another tool:
https://www.qdev.de/?location=mac/exifrenamer&forcelang=en or Graphic Converter
Graphic Converter can read a lot of EXIF data.
Preview can display the EXIF time stamp in the More Info panel.
If you still are seeing issues, take a photo and use the newly taken photo to test against. Move the file to your Mac and if necessary use the Finder to lock the file to prevent modification and try to understand where the data fails to reflect the truth and in which environment the data is truthful.
Again, I am wondering if the date is off in iOS because the software is actually beta so unexpected behavior may indeed occur.
