howto: read file last modified date/time.

Hi

I don't see an out-of-the-box nant file function to read the last modified
date/time of a file into a property.  The opposite of the 'touch' task.
I checked nantcontrib and I didn't see anything there (unless I missed it)

Is anyone away of an existing library or code snippet I can copy/paste that
may accommodate this before I go an re-invent the wheel?

Thanks
Phil
