Caching a data source and showing last refreshed timestamp on analysis

I have a table from a SQL data source that is cached daily using the function in Data Virtualization. I then have an information link using that data source and I want to provide the analysis viewer with the timestamp of the last cache. Do you know how I would go about doing this? I've tried to look in the DVlayer tables to see if theres any timestamp I can point to as a property control but I cant find any data point that looks obvious for this?
