Home/Snapchat Memories wrong date after export
The actual product
Why exported Snapchat Memories have the wrong date
This is the job. Not “how do I press download.” The ZIP you already have sorts as today. Capture time was never in the filesystem date Snapchat wrote.
Where the real date lives
Filename prefix: YYYY-MM-DD, sometimes with a time. memories_history.json: Date as 2017-04-03 22:11:04 UTC. ZIP extra timestamps on some parts. None of those are DateTimeOriginal until a fixer writes them.
What we write
We do not invent GPS. If the JSON has no Location, the file stays without coordinates.
- JPEG: EXIF DateTime, DateTimeOriginal, DateTimeDigitized, GPSLatitude/Longitude when present.
- MP4: mvhd / tkhd / mdhd creation and modification times (Mac epoch) so Apple Photos and Google Photos both see the year.
- ZIP entry dates so Finder/Explorer sort by capture day even before an importer runs.
