# 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.
