I have an M file which obtains data from xls and csv files.  There has been an occurance of these data files not being updated as they should have been and I would like Matlab to issue a warning if the files are over a certain age.

Is there a way I can obtain the last modified date of file using Matlab. 
Looking in help dir and ls only give the file name and fileattrib appears to only give on/off type atrributes such as if it is a hidden file.

What about the datenum field of the structure returned by dir?

That is perfect. Thanks.

How did I miss that when looking through help?
