Yes. There are several formats to represent time.
And when you use in a sitemap.xml, you should represent
time in the former format [1].

You can do it by using a Time#xmlschema method [2].
To use this method, you must do require 'time' module.
See example below:

[2] http://www.ruby-doc.org/core-1.9/classes/Time.html#M000333

$ irb
ruby-1.9.2-p136 :001 > require 'time'
 => true
ruby-1.9.2-p136 :002 > File.mtime( 'test' ).xmlschema
 => "2011-03-30T13:34:40+09:00"
