Lightroom CC: Capture date falls back to previous date after editing

Hi Victoria, thank you for your reply! And you already gave the answer... I've just checked and in grid view, the batch function is available like you wrote. I did this last time in edit view and there you can edit only one photo, even some more are marked in the filmstrip at the bottom. This was my confusion.

Hope the date-time function is working correctly now after the last update. But did not synch with Lightroom classic or mobile yet. Hope this will not reset the date-time settings in some photos. Took me some time to edit the date-time settings of all photos from my last trip only to see that lots of photos were not updated or fell back to the original date-time when opened next time, which messed up the grid view a lot.

And of course, I can share my SysInfo if still needed:

That does sound frustrating Robert, but I'm not quite clear on what's gone wrong. 

You mention a new iPad installation. At what point do the dates get messed up? Take us through the steps?  The dates were right before you installed the iPad app? Was this a fresh download/sync from the cloud, or were you restoring the iPad from a backup? Did all of the dates get messed up or a few random ones? Did they get messed up everywhere, or just in the iPad app?

It's not an issue that's being reported by other people, so it's going to take a bit of detective work to figure out what's going wrong for you.

Thanks for your answer Victoria and sure I can tell the whole story from the beginning to get most detailed info on this issue.

I was on a trip to SEA and forgot to set up the time in my camera. I already had the new Lightroom CC installed on my MacBook but not migrated to the new Lightroom CC yet, I still used Lightroom Classic during the trip. But I had the Lightroom CC App on my iPhone where I developed my mobile photos only. When I came back to Hamburg I migrated to the new Lightroom CC on my MacBook. After a week of migrating and uploading all my photos (about 22000) to the cloud, I recognized that I forgot to set the time in my camera because I saw that the mobile photos which were in the correct time zone automatically were in different positions than my raw files from the camera. Then I found the batch option to set the time at once on a bunch of marked photos in the grid view like you wrote before already. It took me one evening to adjust the time settings and get mobile and camera photos from my trip in the order they should be. Did this on my MacBook. Talking about 2250 photos from the trip all in all. Then after a couple of days when scrolling through the photos in the grid view I saw that at times some random photos appeared not in the correct order. They had the old time settings again. I am not very sure but it seems that this happens after I used the mobile app and used the app on my MacBook again. But might be also when using the desktop app only. Here I'm not very sure. Then I bought a new iPad lately and installed Lightroom CC there as well, everything fresh, no backup. And here I'm pretty sure I ordered all photos once again on my MacBook and waited until synch was finished (blue moving circle indicator in the top right) then opened the iPad App and logged in. After my photos were uploaded to the iPad App I had the mess again on the iPad. Some random photos had their old timestamp again and were not in the correct order. When opened the MacBook App again these photos had the old original timestamp also. Since I couldn't set the date on the iPad I corrected the time settings on the MacBook again.

I'm not very sure in which scenarios this happens because this happens so often in the last weeks but for sure it happens again and again. It feels like there are less and fewer photos which fall back to the old time setting by that time but nevertheless, it is pretty annoying and frustrating to open the app - on MacBook, iPhone or iPad - and see that there are some random photos which have the old settings again.

What makes it even stranger is that this happens randomly. Randomly on time when it happens and randomly on the affected photos. And sometimes to the same photos again where I set the time already two or three times.

Hope I could explain the issue comprehensible so far because it's pretty confusing and English is not my native language.

If you still have any questions or anything is unclear let me know and feel free to ask again. Would be nice to get this issue fixed and have all my photos constantly in the correct order since this is the way the new Lightroom CC orders the photos by default - as far as I understand it.

Thanks Robert (and your English is excellent!)

Classic's involvement is a very good clue, and potentially the source of the bug. Someone in this thread also mentioned date/time issues syncing with Classic.

So are you still using Classic, or is that out of the picture now you've got LRCC installed on your MacBook?  All-CC is a much more closed-loop system and I think you'll find the sync is much more stable there, but it would be useful to know if you hit this issue again without Classic involved.

That might be the problem. I used LRClassic a few times in between because of missing function in LRCC (Panorama). I will keep this in mind and watch if it will happen again after using LRClassic especially.

Thanks a lot Victoria!
