Module: ActiveSupport::CoreExtensions::Integer::Time

Included in:
Integer
Defined in:
lib/gems/activesupport-2.2.2/lib/active_support/core_ext/integer/time.rb

Overview

Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.

These methods use Time#advance for precise date calculations when using from_now, ago, etc. as well as adding or subtracting their results from a Time object. For example:

# equivalent to Time.now.advance(:months => 1)
1.month.from_now

# equivalent to Time.now.advance(:years => 2)
2.years.from_now

# equivalent to Time.now.advance(:months => 4, :years => 5)
(4.months + 5.years).from_now

While these methods provide precise calculation when used as in the examples above, care should be taken to note that this is not true if the result of ‘months’, ‘years’, etc is converted before use:

# equivalent to 30.days.to_i.from_now
1.month.to_i.from_now

# equivalent to 365.25.days.to_f.from_now
1.year.to_f.from_now

In such cases, Ruby’s core Date and Time should be used for precision date and time arithmetic
