It will not work on macOS Mojave (10.14) or earlier as the Photos database format is different.Ĭaution: This app directly modifies your Photos library database using undocumented features. It should work on macOS Big Sur (11.0) and macOS Monterey (12.0) but I have not been able to test this. Photos_time_warp has been well tested on macOS Catalina (10.15). This example sets the date for all selected photos to, subtracts 1 hour from the time of each photo, and sets the timezone of each photo to GMT -07:00 (Pacific Daylight Time). Photos_time_warp -date -time-delta "-1 hour" -timezone -0700 -verbose To use it, open Photos, select the photos for which you'd like to adjust the date/time/timezone, then run photos_time_warp from the command line: Photos_time_warp operates on photos selected in Apple Photos. If you need the functionality in photos_time_warp, I recommend you take a look at osxphotos which offers this same functionality in addition to many other useful tools for working with Photos. I will no longer be maintaining photos_time_warp and will eventually archive this repository. Note: All functionality in photos_time_warp has been added to osxphotos as of. Batch adjust the date, time, or timezone for photos in Apple Photos.
