title: Trying to convert influxdb timestamp in a csv to date and time columns
body: <p>I am migrating an InfluxDB database to mySQL. I have managed to export the influx data to a CSV file, which is great, but now I am stuck with the date and time field which has been given to me.</p>
  <p>I have no idea what format it is in, after doing some research it tells me that it is in epoch time, but using python to try and convert the timestamp to an ISO format, it isn't recognised as a valid timestamp. Any idea how to get this converted. Ideally to separate date and time columns. The data that I have got is something like this :</p>
  <pre><code>time,absoluteHumidity
  1578152602608558363,5.788981747966442
  1578152608059500073,4.769760557208695
  1578152613662193439,5.788981747966442 
  </code></pre>
  <p>And the python that I was using to try and convert it, was this :</p>
  <pre><code>from datetime import datetime, timezone
  
  
  print (datetime.fromtimestamp(1578152602608558363, timezone.utc))
  </code></pre>
  <p>Any help or suggestions would be appreciated !</p>
