Can the creation date of a SHP file be retrieved via a MAPSERVER call?

These days the only data files mapserver hits directly are shapefiles so
this would be
a pretty specific addition (i.e. low priority). What about the
possibility of storing the
last modified in a seperate file and using INCLUDEs in 4.10 to get at
them via metadata?
Then you'd have access to that information via a template. I've not
tested that but it
might work.

I discounted this approach because I would need a separate list of the 
SHP files ahead of time to pass them in to the CGI request.

Right now, the MAP files is the only location where the SHP file is 
referenced.  That's why I was looking for a way to read the change date 
from MapServer.

Each of our layer are set up with their own MAP file rather than one 
large one.  So getting the info From Mapserver seems like the best 
approach in the long run
