Sort by date doesn't work properly.

[ZornHadNoChoice]

Describe the bug
It seems like sort by date order has a resolution of seconds.
I have generated many images with code and the difference in creation date between two consecutive images might be less than a second but it's not 0. I think that Aves treats them as having the same date and sorts them alphabetically.

To Reproduce
Steps to reproduce the behavior:

1. Get some images with the same creation date modulo a few microseconds.
2. They will not be sorted correctly.

Expected behavior
The app (at least internally) should use microseconds to sort images.

Screenshots
Correct sorting on the right.

I'm not sure if downloading these images changes their creation time, but in case it doesn't here are two images to test (you can see the correct order above):

I'll take a closer look tomorrow, but in the meantime I'd like to point out that Aves favours metadata dates, and uses file dates only as a fallback. As I remember, metadata dates (in EXIF and XMP) can have subsecond resolution, if the fields are provided. Otherwise, if you rely on file dates, it's available for media via this field, which is in seconds. Anyway, relying on file dates is a bad idea. The "creation date" you mention is in the Exif, with the subsecond field?

umm, how to say this? I'm nothing but a novice programmer. In other words, I didn't understand your points/don't know about those EXIF things!

I've fixed the precision of the file modified date, but you shouldn't rely on it anyway. If you move files to another device (or for many other reasons), the date will change. Rely instead on metadata dates. You can search for Exif, etc. It's not a programming thing, it's just metadata formats.

Thanks.

Noted. I'll try to find a way to change the metadata.
