Get the Network Time

The following steps describe how to retrieve the current network time using the Time Synchronization service.

1.  Retrieve the instance of AMT_TimeSynchronizationService, where “the “Name” key equals “Intel(r) AMT Time Synchronization Service”.

2.  Invoke AMT_TimeSynchronizationService.GetLowTimeSynch, which returns a uint32 value, Ta0, which is the current Intel AMT network time in UNIX time format.

You can execute this snippet by inserting it into the execution template found here.

  

function GetTimeSync

{

    $timeSynchronizationServiceRef = $wsmanConnectionObject.NewReference("SELECT * FROM AMT_TimeSynchronizationService WHERE Name='Intel(r) AMT Time Synchronization Service'")

    $inputObject = $timeSynchronizationServiceRef.CreateMethodInput("GetLowAccuracyTimeSynch")

    $outputObject = $timeSynchronizationServiceRef.InvokeMethod($inputObject)

    $returnValue = $outputObject.GetProperty("ReturnValue")

    if($returnValue -like "0")

    {

          $ta0 = $outputObject.GetProperty("Ta0")

          return $ta0

    }

}
