My best explanation for this at the moment is that “device_timestamp” is based on the time that the image or video is actually created on the device, and that the “taken_at” field reflects an actual upload time. I need to do a little additional research to verify this is the case, but it’s a reasonable hypothesis for now. 216 weeks ago is not precise enough.
