Quick-n-dirty function to test a NTP Server per Powershell

.. quite simple - just to test if a ntp server works, if you need more accuracy than +/-9sec just match against ",\ (\+|-)00" 

function Test-NTP($ntpserver){
$pinfo=[System.Diagnostics.ProcessStartInfo]::new("$($env:SystemRoot)\system32\w32tm.exe",@("/stripchart","/computer:$ntpserver","/dataonly","/samples:1"))
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$ntptestproc=[System.Diagnostics.Process]::new()
$ntptestproc.StartInfo=$pinfo
$ntptestproc.Start()|Out-Null
$ntptestproc.WaitForExit()
return $ntptestproc.StandardOutput.ReadToEnd() -match ",\ (\+|-)0"
}
