Adjusting EXIF dates

Sometimes EXIF date information on pictures can be incorrect, usually because the clock on the camera is set incorrectly. To adjust a set of pictures with incorrect EXIF date information I run a command similar to:

$ exiftime -v+1y -fw *

This will add one year to all the EXIF date tags in all the pictures in the current directory. The modifiers are y, m, w, d, H, M, and S and they can be adjusted forwards with + or backwards with -.

For complete details, see the man page.
