EXIF Time Shift (JavaFX, Java 24)

exif-time-shift

A desktop app to scan a directory of photos, check the Device/Camera Model, the photos were taken with, and apply a time offset to EXIF DateTimeOriginal and DateTimeDigitized for the selected Device/Camera Model using Apache Commons Imaging (lossless where possible).

Imagine, you and your friend take photos with two cameras. One has a faulty local time set. This allows to select all photos taken with this camera and to correct the time stamps.

Requirements

  • Java 24 (toolchain in Gradle)
  • Gradle 8+
  • JavaFX

Run

Mac + Linux

./gradlew run

Windows

gradlew.bat run

Notes

  • Only JPEG/TIFF EXIF is modified. Other formats are skipped.
  • We write updates losslessly into a temp file and then replace the original.
  • A .bak backup of the original file is created next to it.
