exifdatefilenamer

Takes an offset and a list of paths to JPEG files with EXIF metadata, and generates hard links whose names are based on the file's DateTimeOriginal EXIF attribute with the offset applied.

For example :

2
foo.jpg
bar.jpg

-9
abc.jpg
zxc.jpg

Assuming that the files' DateTimeOriginal is, respectively, 2023:10:19 23:01:00, 2023:12:31 23:35:23, 2023:01:01 06:05:01 and 2023:05:05 19:34:22, this will produce the following :

2023_10_20-01_01_00.jpg -> foo.jpg
2024_01_01-01_35_23.jpg -> bar.jpg
2022_12_31-21_05_01.jpg -> abc.jpg
2023_05_05-10_34_22.jpg -> zxc.jpg

Why?

It's useful if you have files from a multitude of sources whose time is not synchronised, or some of these sources apply different timezone offset rules.

My partner's phone, for example, reverts back to the home network's timezone when in airplane mode. This creates problems when we go abroad and one of our phones is in airplane mode while the other isn't. Generating a series of links like this script does allows showing the images from both sources in the correct order.
