Here is a natural, professional English translation suitable for a bug report (such as filing via Apple's Feedback Assistant): Title / Summary Photos app defaults to creation time instead of EXIF date when region and time format are mismatched Bug Description Photos saved or received in the system Photos app (via downloads, AirDrop, etc.) use the saving timestamp as their capture date instead of preserving the photo's original metadata/EXIF timestamp. Steps to Reproduce Go to Settings > General > Language & Region. Set a Region whose default time format differs from your custom toggle (e.g., set Region to Japan, which defaults to a 24-hour clock, but manually switch the time format toggle to 12-Hour Time). Save or receive an image via AirDrop/download. Observe that the photo's original date metadata is ignored and replaced by the current timestamp. Root Cause Analysis The bug occurs when the device's custom time format (12/24-hour) mismatches the default time format of the selected Region, causing date metadata parsing to fail in the Photos app. Workaround Resetting the time format back to match the Region's default setting resolves the issue. Expected Result The system should correctly parse and preserve original image creation dates regardless of custom region or time format overrides. This issue should be resolved in a future software update. Affected OS Versions iOS 17+ iPadOS 17+ macOS 14 (Sonoma)+
