Unhandled Exception when using GetDeliveredNotifications method

Hi,

I'm trying to get all notifications to delete some of them but when I'm using this code, I got a Exception:

`var notifications = await _toastNotificator.GetDeliveredNotifications();
foreach (var notification in notifications)
{
Console.WriteLine(notification.Title);
}`

> Unhandled Exception
> System.ArgumentOutOfRangeException: Value to add was out of range.
> Parameter name: value

I'm using the last version on nuget 3.3.2.

This error was also present with the 3.2.1 version.

In the source code, I think the problem comes from this line in NotificationBuilder.cs :

`Delivered = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(notification.Notification.When)`

I create the notifications with this code:

`var options = new NotificationOptions`
`{`
` Title = call.CallLevel?.Name,`
` Description = call.Subject,`
` IsClickable = true,`
` AndroidOptions = new AndroidOptions`
` {`
` SmallDrawableIcon = 2130903040// Defined Android Icon`
` }`
`};`
``
`_toastNotificator.Notify(options);`

Do you have any idea why i'm getting this error ?
Unfortunately, I can test only on Android, I cant update my Windows 10 with the last update.
