After upgrading to Mojave, most folders' time stamp is set to 1 Jan 1970

Feedback - macOS - Apple

Please use the link above to submit a bug report to Apple.

The more people submit, the higher the priority this bug will be in Apple's queue.

I find this bug totally unacceptable, as it really causes trouble using Finder and my most important folders.

By the way, the modification date of my buggy folders changed to 04 November 2018, so 1970 ist gone. Still annoying, as all those dates are incorrect.

I doubt that the original dates can ever be recovered. Apple probably overwrote the correct dates.

I have exactly the same problem, iMac 27 5k (late 2014), SSD, macOS 10.14.

iCloud drive sync "Desktop and Documents" turned on.

See screenshot: http://take.ms/RfbHx
Folders and files inside those affected "1970" folders have correct dates.

Note that the affected folders are direct subfolders of Desktop, Desktop being located in iCloud drive.

So this is the hierarchy:

iCloud drive > Desktop > 1970 folder > normal folder

Apple, please fix this bug!

I have exactly the same problem on my 12-Inch Retina MacBook (Mid-2017). I contacted Apple support about this two weeks ago and they seem to have no clue as to what could have caused this error. And more importantly no fix to it.

Same issue here. When upgrading to 10.14.1 (I think it was connected to this upgrade), dates of affected folders changed to current timestamp. See screenshot: http://take.ms/PpqP4

Still not the original folder dates, however. Folders affected are connected via https://www.wellness-heaven.de/

Quite annoying. Apple seems to have lost the info on the original dates, and just reset to current timestamp ...

OK good to know. I have held off upgrading to 10.14.1 until I know more what's going to happen. As a freelance writer I have sorted all my work in recent years in folders so that I easily could trace what I have done chronologically for different clients for invoicing and such.

But since I upgraded to Mojave all that is shot to pieces.

And changing the folder date to the current date would not help at all.

The files in the folders do have the correct dates. So theoretically it should be possible to write a fix that would change the folder date to the creation date of the oldest file in the folder.

But that would require Apple to actually address the problem, which they don't seem to have done so far.

Same problem here. After the update to Mojave most (but not all) folders in Desktop and Documents got 1969 December 31 as the "last modified" date. Tried many things to fix it without much success:

1. Signed out of my iCloud account, then signed back in - dates changed to April 17, 2017 (incorrectly)

2. Deleted CloudDocs folder from Library- no effect

3. Quit icloudd and bird programs from activity monitor - no effect

The most annoying thing is that even if I modify something in the folder with incorrect date (say, remove a file from there), then the modified date changes to "Today", but in about 2 minutes reverts back to April 17, 2017.

I have the same issue with the time stamp, it's a significant problem. All my current project files "date modified" were just uniformly re-stamped to 11/15/18, even though most of them had not been touched.

I use the icloud drive and like to switch between my iMac (late 2013) and new MacBook Pro (both on Mojave) when I travel.

Seriously. Apple. Please address.

It seems that Apples does not have a clue at this point. I've been in contact with support several times. But they don't seem to have any ideas. On top of the previous problems I decided to move from a Macbook 12" to a new Macbook Air. In order to do so I used Migration Assistant and a USB-C to USB-C cable. When the migration was done most of the folder that previously were unaffected changed their dates to November 15 2018 which was the day I performed the migration. And this time the results were even worse since all subfolder in the affected folders also changed date. This was not the case when I updated to Mojave. Then only the top folders, and strangely enough not all but most, were affected. And all changes were copied to iCloud, so the damage seem to be irreversible unless Apple comes up with something. I no longer have any use of sorting my work chronologically. Which is costing me a lot of time and in the long run money.

My issue is that everything in the "Date Added" column is July 22, 2017. It will only show "2017" as the year in the first column. I cannot change it. Because of this issue, I could not find a document I had downloaded within the downloads folder until I did further searches. It doesn't seem anyone has any idea how to fix this. I have an iMac Retina 5k, 27inch, 2017. Doesn't make any sense to me at all.

I used Migration Assistant to copy from a hard drive backup to my new MacBook Pro and… yes, many of the files came over with a Date Modified changed to the migration date -- 18,870 files to be precise. I don't see any rhyme or reason, though it seems like most of the files are older files and a LOT of folders were changed (even if the files inside them weren't).

Both the hard drive backup and the new computer had been updated to 10.14.2.

This is a huge problem for me. I will probably need to re-copy all the folders and files manually and see if that brings them back. Ugh.

Same here. I haven't had the problem of all dates going to 1969 or 1970 or whatever, but I do have the issue described above where if something is modified in an iCloud Drive folder (add or remove a file), the Date Modified changes to "Today" for about 2 seconds, and then reverts back to whatever day it previously had from 2017.

I have the same problem. I found that if I change the name of the folder, hit enter, and then change it back and hit enter again the folder's date will update to the current time. The folder will retain this new date going forward but even if you save new files to it after that, it still doesn't automatically update meaning it doesn't really solve the core problem. At least by changing the folder name and then back again, I have been able to move my most folders up to the top of the date sorted folder list.

Issue persists in 10.14.3
