Not able to find a way to get the last publish date for a content type

Hi,

We are programmatically publishing content types using the content type hub feature of SharePoint 2010. We are able to publish the content type successfully but we are not able to find a way to get the last published date. We don't see any method or property that will give us this information in the ContentTypePublisher class. Any idea as to how this can be achieved?
