"Can't restore time" when extracting on Windows 8.1

[mathstuf]

Something with this zip file, md5: 53c1c32f8f4730538a6d3e9eb5d8589e:

CMake Error: Problem with archive_write_finish_entry(): Can't restore time
CMake Error: Problem extracting tar: ftjam-2.5.2-win32.zip

This has also been seen with some Boost tarballs, so it isn't zip-specific (I'll try and find the tarball we had issues with).

Can also do this if extracting to tmpfs on FreeBSD 11.
Actually no, idk what exactly did it.

/tmp/tmp.EvkSRU1l/update.tar                  100% of  325 MB 3896 kBps 01m25s
[-] Warning: Could not find extra file script.sh.  Skipping validity checks for that file.
./mnt/: Can't restore time
tar: Error exit delayed from previous errors.

At first I did it in tmpfs, got rid of that and still got the error.
If I figure out what causes this, I'll update.

so I just hit this again, and am quite surprised to find my own post. again not finding it either ;-)
things did unpack though. can only suggest retrying if it happens.

Well, there are three different cases when this message is set by archive_write_disk_windows. If the __la_win_permissive_name_w failed, if CreateFileW failed and if SetFileTime failed. A first step would be to check which of thise is the problem. You might want to try adding a printf before each goto settimes_failed and also print GetLastError() with FormatMessage.

It doesn't seem to be Windows-specific based on this comment.

This happens when I tried to 'tar xzf' on exFAT. Works fine on NTFS

Linking this ticket to another which has the goal of making this message non-fatal, since it is regarded in some parts of the code as a "warning"
#1516

@sklaw is right.

Why the he-L it does not recognize exFAT?

[loryruta]

I can confirm it gives the error on exFAT but works fine on NTFS. I just wanted to add a note:

Using Windows 10 PowerShell I'm perfectly able to change the Last Modified time on an exFAT fs, while tar -xvf <archive> -C <out-archive> complains with "Can't restore time".

This issue is still relevant on Windows 10, and for me has had the downstream effect of preventing me from being able to build OpenCV on an exFAT drive. Is there any idea why this would happen specifically with exFAT?

[NullHypothesis]

I ran into this issue in a GitHub workflow that's based on macOS 12, so this does not appear to be limited to Windows. Curiously, the workflow is non-deterministic: it occurs only sporadically.

Update: My problem is discussed in this issue: actions/runner-images#2619 Passing the flag -S to tar fixed the problem for me.

On Windows, you need to compile on an NTFS disk instead of a FAT32 or exFAT disk, then cmake can perform the extract. I guess there's an issue to extract on a FAT32 or exFAT disk.
