Register background task with ToastNotificationHistoryChangedTrigger trigger.

public class MyBackgroundTask : IBackgroundTask
{
    public void Run(IBackgroundTaskInstance taskInstance)
    {
        var deferral = taskInstance.GetDeferral();
        var details = taskInstance.TriggerDetails as ToastNotificationHistoryChangedTriggerDetail;
        if (details != null)
        {
            if (details.ChangeType == ToastHistoryChangedType.Cleared || details.ChangeType == ToastHistoryChangedType.Removed)
            {
                // your code - get current time
            }
        }
        deferral.Complete();
    }
}
