Set EXIF date based on the filename order

[gsur1200]

I want to fix the EXIF data on a group of photos that appear scrambled on Google Photos.
Some have the wrong date/time, some are correct. It's all a mess -- there's no logic to the different timestamps.

But if I look at them on the mac Finder, their order is correct: their filenames have the right order.

Is there a way to:
1) set all the photos to June 1st
2) set a new time for every photo, in a way that keeps the same order I see in the Finder?
      (e.g. every subsequent photo is offset by +1 minute or something..?)

I'm not picky about time accuracy; I just want them to appear in the right order...

Thank you so much for your time.

You can use xnviewmp software. 1 Sort by name, 2 Select files, 3 Tools menu, ... change timestamp (with increment for each file)
For this task, xnviewmp uses exiftool
