title: sqlite: Can I mock the current time `now()` for testing?
body: <p>I build a test suite for a program that runs a lot of SQL statements with <code>now()</code> against a sqlite data base.  I would like to mock the sqlite clock --- to test behaviour that is designed to take several days within one second.  I do not want to touch the system clock.</p>
  
  <p>Is this possible with sqlite?</p>
