Date Time stored in InfluxDB

Today I installed Influx. All data streams nicely into the Influx DB.
But all date time stamps are stored like 1497963150053349888
How can I convert them back to a normal datetime stamp?

If you just want an individual time you can use

$ date --utc -d @1497963150
Tue 20 Jun 12:52:30 UTC 2017

If you want to create graphs, graphana handles all that for you.
