+## Timestamp column type
+
+By default, Rails uses the `timestamp` data type that stores timestamp data without timezone information.
+The `timestamp` data type is used by calling either the `add_timestamps` or the `timestamps` method.
+Also Rails converts the `:datetime` data type to the `timestamp` one.
+
+Example:
+
+```ruby
+# timestamps
+create_table :users do |t|
+ t.timestamps
+end
+
+# add_timestamps
+def up
+ add_timestamps :users
+end
+
+# :datetime
+def up
+ add_column :users, :last_sign_in, :datetime
+end
+```
+
+Instead of using these methods one should use the following methods to store timestamps with timezones:
+
+* `add_timestamps_with_timezone`
+* `timestamps_with_timezone`
+
+This ensures all timestamps have a time zone specified. This in turn means existing timestamps won't
+suddenly use a different timezone when the system's timezone changes. It also makes it very clear which
+timezone was used in the first place.
+
+
