- # 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[http://stdlib.rubyonrails.org/libdoc/date/rdoc/index.html] and
- # Time[http://stdlib.rubyonrails.org/libdoc/time/rdoc/index.html] should be used for precision
- # date and time arithmetic
