title: SQLite DateTime columns accepting any value... normal?
body: <p>I have an iOS app that takes use of SQLite. I use FireFox and the plugin SQLite Manager for managing the database.</p>
  
  <p>Now I have a table like this:</p>
  
  <pre><code>CREATE TABLE "someTable" ("id" INTEGER NOT NULL , "timeOfEvent" DATETIME NOT NULL)
  </code></pre>
  
  <p>I am however able to input practically any value I want into the DateTime column like so:</p>
  
  <pre><code>INSERT INTO sometable (id, timeOfEvent) VALUES (1,'2012-99-99')
  INSERT INTO sometable (id, timeOfEvent) VALUES (2,'yyyy-mm-dd')
  ...etc
  </code></pre>
  
  <p>Why is this possible?</p>
