Unix like systems don't store file creation info[1]. For last
modified, or access time, see the documentation for File.

sort_by it:

Dir.entries(".").sort_by{|c| File.stat(c).ctime}

Or use a Swatz* Transform which is used by sort_by inherently:

Dir.entries(".").map{|c| [c,File.stat(c).ctime]}.sort{|a,b|
a[1]<=>b[1]}.map{|d| d[0]}

* Swatz is a Perl hacker whose full name is Randal Swatz (hope me
remember that correctly).

You mean Randal Schwartz and his Schwartzian transform:

As you said, sort_by implements that already, so it's faster to use it
instead directly.
