How to set culture in PowerShell?

I think this will work:

$currentThread = [System.Threading.Thread]::CurrentThread
$culture = [System.Globalization.CultureInfo]::InvariantCulture
$currentThread.CurrentCulture = $culture
$currentThread.CurrentUICulture = $culture

This idea came from:

This is the function I use for testing string/formats in other cultures:

function Using-Culture (
  [System.Globalization.CultureInfo]
  $culture = (throw "USAGE: Using-Culture -Culture culture -Script {...}"),
  [ScriptBlock]
  $script = (throw "USAGE: Using-Culture -Culture culture -Script {...}"))
{
    $OldCulture = [Threading.Thread]::CurrentThread.CurrentCulture
    $OldUICulture = [Threading.Thread]::CurrentThread.CurrentUICulture    
    try {        
        [Threading.Thread]::CurrentThread.CurrentCulture = $culture        
        [Threading.Thread]::CurrentThread.CurrentUICulture = $culture        
        Invoke-Command $script    
    }    
    finally {        
        [Threading.Thread]::CurrentThread.CurrentCulture = $OldCulture        
        [Threading.Thread]::CurrentThread.CurrentUICulture = $OldUICulture    
    }
}
