title: convert timestamp from one valid RFC3339 format to another in Go
body: <p>I have timestamps strings in this format <code>2020-01-17T14:41:56.393+0530</code> and I want them converted into this format <code>2019-01-18T04:32:03Z</code></p>
  
  <p>The time.Parse method <a href="https://golang.org/pkg/time/#Parse" rel="nofollow noreferrer">documentation</a> on that godoc says that these are both valid RFC3339 formats but how do I convert them from this form to the Z form?. </p>
  
  <p>Actually want I want to do is find out whether a certain timestamp in this format <code>2020-01-17T14:41:56.393+0530</code> lies within a range of two timestamps that are in the z format <code>2019-01-18T04:32:03Z</code></p>
