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
