title: How to set Knex date to 30 days in the future
body: <p>I think this question is simple really but I wasn't able to find an answer for it.</p>
  
  <p>In Knex i could set a timestamp in my database with <code>knex.fn.now()</code>
  However now I have a need to set a date 30 days after <code>now</code> is this as simple as <code>knex.fn.now() + 30</code> work or is there another trick?</p>
  
  <p>Any help is appreciated even a link to a different source.
  Thank you in advance</p>
