How to shift Creation Date/Date Created for media in Adobe CC?

I have footage shot across 2 phones and a GoPro.

When going abroad, the filenames save according to local time, but the ‘Creation Date’ saves according to my home’s time (London, BST). For example: filming at 14:32 in Germany creates a file called “20260501_143236.mp4” with the creation date 01/05/2026 13:32 🙃 … 
This, however, does not happen with the GoPro, which saves the files according to local time (in this example, 14:32)

So the goal is: I want to change all the ‘Created/Capture’ times from phone media by 1 hour, so I can sort and filter everything chronologically in Premiere.
I cannot sort/filter by filename, because GoPros save with a different naming convention unrelated to DDMMYYYY_HHMMSS

I tried using Adobe Bridge to shift the Date Created by 1 hour. It then looks correct (the Date Created matches the filename) in Bridge, but this then not updated in Premiere Pro: 

In PP I have Offline/Re-linked the media, I completely deleted from Project and re-imported, and of course restarted everything. “20260501_143236.mp4” still has the Creation Date 01/05/2026 13:32.

THEN, when I right click>File Info in Bridge, I see that ‘Creation Date’ is still incorrectly 13:32. Meaning that (1) there are two different things: Date Created and Creation Date, (2) I can only edit one of these in Bridge, and (3) the one I can edit is not the one that is pulled through by Premiere Pro.

Why is this? Is there a way to do this? Bridge? Premiere? Media Encoder?
