Add Date Property to Search-EZTV results

[assives]

This is great.
I've been using it since I saw it here last week.
Any way to get the date or age of the link in? I can see it in the API but can't work out how to search on the API. I have got the search down pat but can't find dates in it.
An example of what I am thinking
Search-EZTV -filter "Silicon Valley" | where{$_.age -lt (get-date).AddDays(-1)}
