+      # 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(: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:
