Duration is an immutable type that represents some amount of time with accuracy in seconds.

A lot of the code and inspirations is borrowed fromdurationlib, which is amutable Duration type with lot more features.

If you use ruby-duration and want to take over the project, let me know.

• Representation of time in weeks, days, hours, minutes and seconds.
• Construtor can receive the amount of time in seconds or a Hash with unit and amount of time.
• Format method to display the time with i18n support.
• Mongoid serialization support. Userequire 'duration/mongoid'.
• Tested on mri 1.9.3 and jruby. Kudos to rvm!

Duration.new(100) => #<Duration: minutes=1, seconds=40, total=100>Duration.new(:hours => 5, :minutes => 70) => #<Duration: hours=6, minutes=10, total=22200>

Duration.new(:weeks => 3, :days => 1).format("%w %~w and %d %~d") => "3 weeks and 1 day"Duration.new(:weeks => 1, :days => 20).format("%w %~w and %d %~d") => "3 weeks and 6 days"

Duration.new(:weeks => 1, :days => 20).iso8601 => "P3W6DT0H0M0S"Duration.new("P6DT5S") => #<Duration: days=6, seconds=5, total=518405>

The current version of this gem supports Mongoid >=3.0.0.For lower Mongoid versions try:

• < 3.0.0 tagv2.1.4
• < 2.1.0 tagv1.0.0

    require 'duration/mongoid'    class MyModel      include Mongoid::Document      field :duration, type => Duration    end

The current version of this gem runs only on Ruby Versions >= 1.9.3.If you are running a older version of Ruby try:

• tagv2.1.4

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in afuture version unintentionally.
• Commit, do not mess with rakefile, version, or history.(if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
