Steps to reproduce

What date is wrong?

 PS > & {
 >> $format = 'yyyy-MM-dd HH:mm:ss'
 >> (Get-Date (stat -c %w /root) -f $format) + " # $(which stat) 'birth time'"
 >> (Get-Item /root).CreationTime.ToString($format) + " # CreationTime"
 >> (Get-Date (stat -c %y /root) -f $format) + " # $(which stat) 'last modified time'"
 >> (Get-Item /root).LastAccessTime.ToString($format) + " # LastAccessTime"
 >> (Get-Item /root).LastWriteTime.ToString($format) + " # LastWriteTime"  
 >> }
2021-03-10 22:31:43 # /usr/bin/stat 'birth time'
2022-06-04 23:48:49 # CreationTime
2022-06-04 23:48:49 # /usr/bin/stat 'last modified time'
2021-03-10 22:35:51 # LastAccessTime
2022-06-04 23:48:49 # LastWriteTime

Expected behavior

CreationTime must be equivalent to the native `stat` birth of file

Actual behavior

Creation time equivalent `stat` last modified time

PS. UnixStat also does not return proper datetime of file creation.

CreationTime comes from the .NET FileInfo type. If that value is incorrect, you'll need to open an issue here: https://github.com/dotnet/runtime

Yes, System.IO.DirectoryInfo and FileInfo give wrong information.

Can you check on latest pwsh build?

[237dmitry]

The same result, 7.3.0-rc.1

PS. But there is also good news, [console]::ReadKey() has learned to correctly recognize arrow keys ))

Problem still exists in PowerShell 7.4.0-preview.4. But as @SteveL-MSFT indicated, this is a .NET problem. See dotnet/runtime#42372.

The WG discussed this and agree this is a .NET issue.
