Move images in time! (and by that I mean their EXIF date data)
timewarp -folder myfolder [-years 1] [-months 1] [-days 1]
I recently bought a new camera and took hundreds of pics with it, but they wouldn't show up in my gallery or google photos. After days of wondering what is wrong, I realized I set my camera's date to 2021 instead of 2022 when setting it up and decided to make this to fix it!
Initially this was written for my own use, so it only supported Macs with Xcode stuff installed, but now I updated it to work with the EXIF format instead, so it should hopefully work with any camera image .
You can still access the old branch here if you for some reason want to change creation dates of files on a Mac with Xcode command line tools installed.
