I realized issues with date handling on Nextcloud Photos with images uploaded from my iPhone.
I hope my detailed description could help in fixing.

To Reproduce Steps:

1. Upload photos from iPhone (11 - iOS 16.02) to my self hosted Nextcloud (version 25.0.5 - running on Ubuntu 22.0.4)
2. Open photos with iPhone App (version 4.7.0.23) and select 'Sort by newest' option:
   Some photos taken in 12.2022 are shown as photos from 03.2023 while others are shown correctly in 12.2022.
   2/b.) When selecting the 'Sort by name (from Z to A)' option the order is correct.
3. Check the photos on the Nextcloud Photos web UI (Chrome and Edge behavior is the same):
   Some photos taken in 12.2022 are shown as photos from 03.2023 while others are shown correctly in 12.2022.
   3/b.) On the web UI there is no 'Sort by name (from Z to A)' option.

Some more details about two sample photos:

A.) Problematic photo from 12.2022 shown together with 03.2023 photos:
File name on iPhone: IMG_8292.JPG
File name on Nextcloud storage: '22-12-30 20-21-11 8292.jpg'
Exif Info:
File Modification Date/Time : 2023:03:26 18:44:54+00:00
File Access Date/Time : 2023:03:31 15:58:08+00:00
File Inode Change Date/Time : 2023:03:31 15:31:24+00:00
...
Modify Date : 2022:12:30 20:21:11
Host Computer : iPhone 11
...
Date/Time Original : 2022:12:30 20:21:11
Create Date : 2022:12:30 20:21:11
...

B.) Photo from 12.2022 shown correctly together with 12.2022 photos:
File name on iPhone: IMG_8277.JPG
File name on Nextcloud storage: '22-12-28 12-48-55 8277.jpg'
Exif Info:
File Modification Date/Time : 2022:12:28 20:11:58+00:00
File Access Date/Time : 2023:03:31 17:23:22+00:00
File Inode Change Date/Time : 2023:03:31 15:30:30+00:00
...
Modify Date : 2022:12:28 12:48:55
Host Computer : iPhone 11
...
Date/Time Original : 2022:12:28 12:48:55
Create Date : 2022:12:28 12:48:55
...

Conclusion:
1.) Nextcloud gets correctly the creation date and this information is written into the file name used by Nextcloud.
2.) Nextcloud is using the Exif info 'File Modification Date/Time' to time sort the images what is causing problem by modified images.
