4 # Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.
6 # These methods use Time#advance for precise date calculations when using from_now, ago, etc.
7 # as well as adding or subtracting their results from a Time object. For example:
9 # # equivalent to Time.now.advance(:months => 1)
12 # # equivalent to Time.now.advance(:years => 2)
15 # # equivalent to Time.now.advance(:months => 4, :years => 5)
16 # (4.months + 5.years).from_now
18 # While these methods provide precise calculation when used as in the examples above, care
19 # should be taken to note that this is not true if the result of `months', `years', etc is
20 # converted before use:
22 # # equivalent to 30.days.to_i.from_now
23 # 1.month.to_i.from_now
25 # # equivalent to 365.25.days.to_f.from_now
26 # 1.year.to_f.from_now
28 # In such cases, Ruby's core
29 # Date[http://stdlib.rubyonrails.org/libdoc/date/rdoc/index.html] and
30 # Time[http://stdlib.rubyonrails.org/libdoc/time/rdoc/index.html] should be used for precision
31 # date and time arithmetic
