Description Holmes 2025-01-23 00:49:36 UTC 
SUMMARY
On Arch Linux, Ark doesn't show the date column for 7zip archives anymore.

It last worked before the "p7zip" package got replaced by the "7zip" package.

On other archive formats it shows the date column like zip and tar.

Additionally, on .rar archives the date column is also missing.

STEPS TO REPRODUCE
1. Have 7zip installed instead of p7zip
2. Open an 7zip archive in Ark
3. The date column will be missing, it will not be missing when using p7zip instead

OBSERVED RESULT
Date column missing

EXPECTED RESULT
Date column should be still there like in .zip and .tar

Comment 1 2wxsy58236r3 2025-01-25 05:16:07 UTC 
From 7-Zip's version history (src-history.txt):

> 22.00          2022-06-16
> -------------------------
> - 7-Zip interfaces now support high precision (1 ns) timestamps with reserved
>   fields of tagPROPVARIANT (VT_FILETIME).

If a file has high precision timestamps (e.g. 7z2409-src.7z), 7-Zip >= 22.00 shows:
> Modified = 2009-10-08 18:12:00.7968750
p7zip 16.02 shows:
> Modified = 2009-10-08 18:12:00

If a file does not have high precision timestamps (e.g. attachment 141089 [details]), 7-Zip >= 22.00 shows the same as p7zip 16.02:
> Modified = 1993-03-16 19:33:38

Maybe this line is causing the issue?

Comment 3 Holmes 2025-03-02 03:15:46 UTC 
Is there any progress being made so far? For me it appears the merge request is stuck open for over a month and nobody seems to care.

Remove nanoseconds from timestamp

On 7-Zip >= 22.00, timestamps may contain nanoseconds, which breaks parsing.

Keep only the first 19 characters to remove any nanoseconds.
