Images Date/Time Exif Field is sometimes populated with incorrect value

Bug Description

I"ve noticed that when I download images and then copy them to my phone my gallery app will place some photos at the bottom of the gallery presumably because it defaults the time/date to 1970. I'm not sure if there is just some edge case where the UTC value isn't converted correctly or it's populated it with some other number. For exmample on a photo I downloaded today the value in the DateTime field is: bb2de2b328d9ab2466ee65205def4604b8b98ac5b6937108db7a98ca8b1c9a73.

Expected behavior

Photo would download with either the TimeDate of when the Content Creator took it or a value of when the downloader grabbed it.

Actual behavior

Field is populated with a value that gallery apps can't parse/understand.

Software : 585723579199397888 (File ID)
Modify Date : dc474f8968a885a1e419dfd3a78e6ae1366e194dd6892d4ab275b920ce776388 (File Hash)

The above lines are because you have "metadata_handling = Advanced" in your config.ini file. It's adding the file hash and id to the exif data section of the image file. You might want to set it to "metadata_handling = Simple" it makes the file name longer by adding the ID and Hash to the file name instead of the exif data. (not ideal but it might help the issue you are having)

You might want to check out this bug I found when using the advanced metadata handling #172 basically it is overwriting images in single post sets because of the way fansly marks the date and time on the images and this downloader uses that info in the file name.

Thanks for the info. I'd be okay with the FileID in the name but not both. Duplicates don't bother me enough to warrant a 100+ character name. Having the correct post date in the right spot is more important to me. I'm overwriting the hash in the modify date section anyway for the file on my phone otherwise it sits at the bottom of the gallery in random years. Maybe an option to put the data in a different field like 'Artist', 'Copyright', 'Make', Model', or 'User Comment'?

Assuming you are using the python version and not the exe packaged version, you could try play with these lines in the "metadata_manager.py" script.

86: custom_tag_mapping = {
87: 'Exif.Image.Software': 'ID',
88: 'Exif.Image.DateTime': 'HSH'
89: }

139: custom_tag_mapping = {
140: 'ID': 'Exif.Image.Software',
141: 'HSH': 'Exif.Image.DateTime'
142: }

Change Exif.Image.DateTime to Exif.Image.Model
