Log Message:
Update ruby-tzinfo pakage from 0.3.20 to 0.3.22.

== Version 0.3.22 (tzdata v2010j) - 29-May-2010

* Corrected file permissions issue with 0.3.21 release.

== Version 0.3.21 (tzdata v2010j) - 28-May-2010

* Updated to tzdata version 2010j
  (http://article.gmane.org/gmane.comp.time.tz/3225).
* Change invalid timezone check to exclude characters not used in timezone
  identifiers and avoid 'character class has duplicated range' warnings with
  Ruby 1.9.2.
* Ruby 1.9.2 has deprecated "require 'rational'", but older versions of
  Ruby need rational to be required. Require rational only when the Rational
  module has not already been loaded.
* Remove circular requires (now a warning in Ruby 1.9.2). Instead of using
  requires in each file for dependencies, tzinfo.rb now requires all tzinfo
  files. If you were previously requiring files within the tzinfo directory
  (e.g. require 'tzinfo/timezone'), then you will now have to
  require 'tzinfo' instead.
