Description nyanpasu64 2022-02-13 05:39:33 UTC 
SUMMARY
When I extract a ZIP, and a folder contains no files (is empty or only contains folders), the folder's access time is set in the future.

(4444523-03-02 04:58:56.000000000 -0800)

STEPS TO REPRODUCE
1. Download the attached .zip file.
2. Open it in Ark and extract all. Alternatively, extract it using Dolphin's "Extract archive here, autodetect subfolder".
3. Run `stat folders-only`. Optionally check `folders-only/empty` and `folders-only/has-files` as well.
4. Try viewing the folder in Wine.

OBSERVED RESULT
When extracting folders without files inside, their access time is in the future. If extracted in Ark, the access time is 4443302-06-30 03:35:44.000000000 -0700. If extracted using Dolphin, the access time is 4444521-01-12 12:13:04.000000000 -0800.

Wine applications cannot access the contents of folders with access times past 2038, failing with errno 75 EOVERFLOW. I think this is a Wine bug.

EXPECTED RESULT
The access time of folders without files inside is reasonable.

Comment 7 Albert Astals Cid 2022-02-14 10:01:42 UTC 
Let's duplicate it the other way around given how the fix i prepared refers to this bug number and not the other one.
