title: SQlite3 — SQL datetime stamps
body: <p>Am I right in thinking that SQL does intrinsically store a date/time stamp for each commit? i.e., that I have to allow for recording this information as part of my schema design?</p>
  
  <p>It will take a certain amount of space to store this information explicitly (using <code>CURRENT_TIMESTAMP</code> or my own timestamp), and if there's a way of accessing comparable information in some internal database setting, I'd do that instead. I'm working with SQLite3 at the moment.</p>
