title: Convert from JS timestamp to Postgresql Timestamp with time zone
body: <p>I have a simple <code>t = Date.now;</code> which goes to Postresql <code>t_time</code> column declared as <code>timestamp with time zone</code> via REST API.
  I got the error:<code>date/time field value out of range</code>.</p>
  
  <p>I <strong><em>can't</em></strong> use the answer from this <a href="https://stackoverflow.com/questions/42876071/how-to-save-js-date-now-in-postgresql">post</a> as I don't write raw SQL but use ORM(Knex.Js). Calling db only to make the conversion looks like an overkill to me. Any other solution in js?</p>
  
  <p>How come I can't find a convertor? Am I missing something?</p>
  
  <p><strong><em>Note:</em></strong> I just need date and time as hh:mm:ss, I don't need milliseconds.</p>
