The missing Ruby method to print out time difference (duration) in year, month, week, day, hour, minute, and second.

TimeDifference

TimeDifference is the missing Ruby method to calculate difference between two given time. You can do a Ruby time difference in year, month, week, day, hour, minute, and seconds.

Installation

Add this line to your application's Gemfile:

gem 'time_difference'

And then execute:

$ bundle

Usage

Get the time difference in year

start_time = Time.new(2013,1)
end_time = Time.new(2014,1)
TimeDifference.between(start_time, end_time).in_years
=> 1.0

Get the time difference in months

start_time = Time.new(2013,1)
end_time = Time.new(2014,1)
TimeDifference.between(start_time, end_time).in_months
=> 12.0

Get the time difference in each component

start_time = Time.new(2013,1)
end_time = Time.new(2014,1)
TimeDifference.between(start_time, end_time).in_each_component
=> {:years=>1.0, :months=>12.0, :weeks=>52.14, :days=>365.0, :hours=>8760.0, :minutes=>525600.0, :seconds=>31536000.0}

If you would like an overall estimated time component, use in_general (not that accurate)

start_time = Time.new(2013,1)
end_time = Time.new(2014,1)
TimeDifference.between(start_time, end_time).in_general
=> {:years=>0, :months=>12, :weeks=>0, :days=>5, :hours=>0, :minutes=>0, :seconds=>0}

Supported time difference includes

in_years
in_months
in_weeks
in_days
in_hours
in_minutes
in_seconds
