Nextcloud 13 show's wrong/old timestamp on uploaded files

Nextcloud version (eg, 12.0.2): 13.0.0
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.18 (Ubuntu)
PHP version (eg, 7.1): PHP 7.0.22-0ubuntu0.16.04.1

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Select multiple files i do more then 10, drag them to your nextcloud browser window.
  2. The files gets transferred but the progress bar will dissapear. (Made another bug report for that)
  3. The timestamp on the far right of the files is from months to years ago, i am thinking it grabs the timestamp from the files and this is unwanted behavior.

The output of your Nextcloud log in Admin > Logging:

Only updater stuff from the update from 12.0.5 to 13.0.0.

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

Not needed.

The output of your Apache/nginx/system log in /var/log/____:

Nothing noteworty.

I have this issue as well on Nextcloud 14.0.3 and Windows 10 Pro. Showing “5 years ago” and then “2 years ago” on a separate install. Must be a bug?
