Google Photos uses `datetime_original` EXIF tag to sort photos. If using a physical camera etc, the times can be wrong. Fix them by running this with the `exif` library on PyPI.

fix_times.py

import datetime as dt
from pathlib import Path
from typing import NoReturn

from exif import Image


TIMEDELTA = -dt.timedelta(hours=8, minutes=12, seconds=10)
DATE_FORMAT = "%Y:%m:%d %H:%M:%S"  # Verify


def process_photo(file: Path, timedelta: dt.timedelta) -> NoReturn:
    with open(file, "rb") as f:
        img = Image(f)  

    original = dt.datetime.strptime(img.datetime, DATE_FORMAT)
    adjusted = original + timedelta
          
    img.datetime = adjusted.strftime(DATE_FORMAT)
    img.datetime_original = img.datetime  
    img.datetime_digitized = img.datetime  
      
    with open(file, "wb") as f:  
        f.write(img.get_file())


if __name__ == "__main__":
    for file in Path(".").glob("*.jpg"):
        process_photo(file, TIMEDELTA)
