//! const now = DateTime.now();
//! std.debug.print("{}\n", .{now}); // 1977-05-25 20:48:00
//! std.debug.print("{%d %B %Y at %I}:{%M %p}\n", .{ now, now }); // 25 May 1977 at 08:48 PM
//! // NOTE: the format string has to be split in two, because `:` is a special character in fmt

A small script to fix the datetime of jpg files in a directory.
It copies the exif datetime to the file's mtime and vice versa.

This can fix various importing issues with photo management software (e.g. Google photos).


NOTE: This script uses the piexif library to read and write exif data, you will need to install it.

NOTE 2: This script will overwrite the mtime of the files. If you use the
