Kodi show date as 1969-12-31 with WebDAV and CJK locales on Mac

Bug report

Describe the bug

Kodi on Mac display all file date as "1969-12-31" with WebDAV source and CJK locales.

Expected Behavior

Display correct dates as in English Locale / WebDAV.

Actual Behavior

All files have the invalid date "1969-12-31" with WebDAV and CJK locales.

To Reproduce

1. Install MacOS 64bit version kodi
2. Into Videos/Files/'Add videos' to add a WebDav source. For examples "Incoming"
3. Into Settings/Interface/Regional/Language to Chinese or Japanese or Korean. for example Chinese.
4. Into Videos/Files/Incoming ("视频/文件/Incoming")
5. Sort("排序") by Date("日期")
6. You can see all files have the invalid date "1969-12-31".

BTW:
The bug happens no matter how I set the short date format in Regional.

Debuglog

I think there is no meaningful log, because no Error/Warning are reported by kodi itself.

@kirbyzhou I am not able to reproduce the issue on Debian:

@fuzzard can you try reproducing this? I can write an extended test case here.

It works correctly on Android.
I can only reproduce it on macos.

This is a duplicate issue to this where the OP has already posted... #17309

[basilgello]

@KarellenX there were two bugs in there… and this bug affects 64-bit osx builds while the bug which gets fixed by #18727 manifests on 32-bit everywhere.

Well i can confirm the issue. What i can also see is this effects every language other than english when used with a webdav source, not just CJK based languages. When English (or variants like English (Australia)) are used, dates are shown correctly.

The FileItems have the correct parsed CDateTime corresponding to the file times, but for whatever reason the display label doesnt show it and reverts back to epoch - 1 (ie 31/12/1969).

Same content via another source (NFS/SMB) works, so looks to be dav specific. I dont know enough about the guilib side of things to trace back where the label is going wrong.

Edit:
Also isnt skin dependant. Tried another skin from repo (AppTV), same fault, so definitely something with the label for the date in core.

[fuzzard]

Also confirming that #18727 has no effect on the label date, so i dont think the issue is due to date handling as such

[kirbyzhou]

Any fix?

Bug still happens at Kodi-19.4

@fuzzard or @basilgello Do you have time to look at this related issue... https://forum.kodi.tv/showthread.php?tid=368277

Not really sure what to do for him to resolve it.

@KarellenX The topics you linked are not related to webdav. As I mentioned in the issies, there are two separate bugs related to date and time. webdav bug is separate from what #18727 resolves.
