Restarting the Osmo (NOT a cold start from a re-connected battery, or a swap to another one) then taking photos or videos will result in those files having the timestamp of 1/1/2014 12:00 AM, both in the filesystem and in the EXIF data. Multiple shots will see a normal progression of time, of course. This issue can seriously screw up a photographer's organization and workflow, so be warned.

The time will not be corrected until the DJI Go app successfully connects.

To ensure you have the proper date and time, go to the main screen of the DJI Go app, and wait for connection confirmation - you don't need to press the "Camera" button. You might notice a slight delay if you immediately press the shutter to take a picture - I think this is the Osmo syncing with the app.
This is a huge shame as I would like being able to whip out the Osmo, turn it on then take a video/photo without even unlocking the gimbal. Sometimes time isn't on your side and you just have to take what you can. The Osmo is fast at booting - you can take a photo within five seconds of a cold start - so this flaw is exasperating.

DJI-Amy: Can this be fixed? I'm hoping this is just an oversight.

For the current design, the camera don't have the timer or GPS module, so it can only get time from the mobile device. I will report your need to the engineers. Thanks.

Thanks Amy. It's something people don't think about until it's too late, hence the warning.

Fast boot making Osmo good camera for shots, when "things happens", but not anymore with App.
When I import my yesterday's shots to computer, I feel space time continuum disorder :O. It is really, difficult, to fit into shots makes with another camera, that has time stamps.
Is it possible to include timer in next release, or we will be stuck "by hardware design"?
DJI, please.

We will take good consideration about it, it's still in review process. It may take some time. Thanks for your suggestion!

Thank You for response, fingers crossed

Any update on this feature? I had the same experience that none of the recordings I did without the app had a proper timestamp. That's pretty annoying, when you have to put it in the right order later...
Thanks!
