diff.patch returns wrong dates in Python 3.10

Empieza en la ruta diff.patch que formatea las fechas mostradas y sigue cómo se serializan las marcas de tiempo de Arrow. Reproduce la salida con Python 3.10 y arrow==1.2.2; después, verifica que diff.patch contenga valores de marca de tiempo en lugar de una representación de bound-method.

The newest version of arrow library doesn't have timestamp property anymore, only method.

When I try to run the pygit2 with latest arrow (arrow==1.2.2) I get this in the output of diff.patch:

As you can see there is only a reference to method instead of value.
