LastAccessTime always returns the same value

I have what I believe to be a straightforward command to list files and the times associated with them with the command below:

$FileList = Get-ChildItem  -Path $DrivePath -Recurse -Include *.png,*.xlsx `
        | Select-Object Name, Length, DirectoryName, IsReadOnly, LastAccessTime, LastWriteTime
    foreach ($File in $FileList) 
    {
        $MyDate = get-date -format g;
        $Out = New-Object PSObject
        $Out | Add-Member NoteProperty Name              $File.Name;
        $Out | Add-Member NoteProperty Length            $File.Length;
        $Out | Add-Member NoteProperty DirectoryName     $File.DirectoryName;
        $Out | Add-Member NoteProperty IsReadOnly        $File.IsReadOnly;
        $Out | Add-Member NoteProperty LastAccessTime    $File.LastAccessTime;
        $Out | Add-Member NoteProperty LastWriteTime     $File.LastWriteTime;
        $Out | Add-Member NoteProperty DateGathered      $MyDate;
        #Write-Output "now working on $File.FullName";
        $OutArray += $Out
    }  # foreach ($File in $FileList)

    $OutArray | export-csv $DestinationFile -NoTypeInformation;

If the true LastAccessTime is more recent than that, it will output the more recent time, but my attempt is to only read LastAccessTime, not modify it.

Any ideas why the setting is being changed?
