 Huh? Checking the logs, we see that the two commands above correspond to
 the following queries:
 
-    INSERT INTO "goals" ("updated_at", "description", "created_at") VALUES('2008-09-09 19:32:57', 'Run a mile', '2008-09-09 19:32:57') SELECT * FROM "goals" WHERE created_at < '2008-09-09 15:33:17'

 **Rule of thumb:** always use TimeWithZone in your Rails projects. Date,
 Time and DateTime simply don't play well with ActiveRecord. Instantiate
 it with `Time.zone.now` and `Time.zone.local`. To discard the time
 element, use `beginning_of_day`.

 Since it's a subclass of Time, interpolating a range of TimeWithZone
 objects fills in every second between the two times --- not so useful if
 you need a date for every day in a month:
 
-    >> t = Time.zone.now => Tue, 09 Sep 2008 14:26:45 EDT -04:00 >> (t..(t + 1.month)).to_a.size [9 minutes later] => 2592001 
+
+```
+>> t = Time.zone.now
+=> Tue, 09 Sep 2008 14:26:45 EDT -04:00
+>> (t..(t + 1.month)).to_a.size [9 minutes later]
+=> 2592001
+```
 
 Fortunately, the desired behavior is just a monkeypatch away:
 
-    class ActiveSupport::TimeWithZone def succ self + 1.day end end >> (t..(t + 1.month)).to_a.size => 31 
+```ruby
+class ActiveSupport::TimeWithZone
+  def succ
+    self + 1.day
+  end
+end
+
+>> (t..(t + 1.month)).to_a.size
+=> 31
+```
