If by "date of file" you mean the date of the book file(s) in the library then you can see them using a custom column "built from other columns". The template is

Code:

program: formats_modtimes('yyyy-MM-dd')

You can change the format of the displayed date to whatever you want. For example

Code:

program: formats_modtimes('yyyy-MM-dd hh:mm:ss')

shows the time using a 24-hour clock, resulting in a column that contains

Code:

MOBI:2013-10-25 09:06:35,EPUB:2013-10-12 18:25:52,PRC:2012-02-12 10:02:28

if the book has all of .mobi, .epub, and .prc formats.

Be aware that this kind of column can slow down calibre's GUI because the gui must look up the modtime of every book format. Experience indicates that this usually isn't a problem with under 1000 books. YMMV.
