st: capture the date associated with a specific file

[E Michael Foster <emfoster@uab.edu>]

Any way to capture the date stamp of a file in the directory where one is working?  
I have a little code in profile.do that I want executed depending on the modification date of some file in the stata directory.

Anyway to do that?

Many thanks Nick. 

-encode- worked fine.
