Request approval date in Powershell

Question

Hello,

I'm writing another approval cleanup script but i cannot seem to find the attribute I am looking for.
When u check the Adaxes Console u can see a request date for each approval.

When i loop through my approvals with powershell i need to remove the approvals for a certain task after 15 days.
I can find a creationdate attribute on the request, but it is not the same date as shown on the request date.
Is there another attribute i am missing for the moment?
Here is my code:

[Reflection.Assembly]::LoadWithPartialName("Softerra.Adaxes.Adsi")

$admNS = New-Object("Softerra.Adaxes.Adsi.AdmNamespace")
$admService = $admNS.GetServiceDirectly("localhost")

$teller = 0

# Bind to the Approval Requests container
$containerPath = $admService.Backend.GetConfigurationContainerPath(
    "ApprovalRequests")
$container = $admService.OpenObject($containerPath.ToString(),
    $NULL, $NULL, 0)

# Get all pending approval requests
$requests = $container.GetApprovalRequests("ADM_APPROVALSTATE_PENDING")

# Iterate through the requests
foreach ($requestID in $requests)
{
    # Bind to the approval request
    $guid = New-Object "System.Guid" (,$requestID)
    $guid = $guid.ToString("B")
    $requestPath = "Adaxes://<GUID=$guid>"
    $request = $admService.OpenObject($requestPath, $NULL, $NULL, 0)
}
