title: Should I use threeten instead of joda-time
body: <p>I came across <a href="https://blog.joda.org/2009/11/why-jsr-310-isn-joda-time_4941.html" rel="nofollow noreferrer">https://blog.joda.org/2009/11/why-jsr-310-isn-joda-time_4941.html</a>.</p>
  
  <p>1) I am currently migrating Java Calendar to joda-time. I was wondering, should I use threeten instead of joda-time? Is threeten production ready?</p>
  
  <p>2) Can threeten library and joda-time libraries exist together in a same application? As I am using some 3rd parties libraries, which is using joda-time library too.</p>
  
  <p>3) Will joda-time become an abandon project since there is threeten?</p>
