title: Getting wrong year when tryting to convert unix seconds to a readable format
body: <p>I'm trying to convert a timestamp from a datetime input to a readable format. The timestamp is in unix seconds. When I try to convert the timestamp with momentJS, I get a completely different year (in this case 3990). How can I get the right year. The date is fully correct. I have some images below. First one is the value given on a converter website. Second image is console.log of the timestamp from the database, and last picture is what is displayed on the page.</p>
  <pre><code>{events.map((data) =&gt; {
                              console.log(data.date)
                              return (
                                  &lt;li key={data.key} className=&quot;event-card&quot;&gt;
                                      &lt;Link className=&quot;eventlink-card&quot; to={{
                                          pathname: `/hendingar/${data.key}`,
                                          state: {passedData: data}
                                      }}&gt;
                                              &lt;h1 className=&quot;event-title&quot;&gt;{data.name}&lt;/h1&gt;
                                              &lt;p className=&quot;event-date&quot;&gt;{moment.unix(data.date).format('DD/MM/YYYY')}&lt;/p&gt;
                                      &lt;/Link&gt;
                                  &lt;/li&gt;
                              )
                          })}
