Feeds - Data viewer interval?

When in the feeds I want to check the data that its receiving so I go into the Data viewer for that feed and it shows me a graph and on the bottom some useful information. At the very bottom there’s the API request which I can see the CSV output. This is whats filled in automatically :slight_smile:

GET http://192.168.2.9/emoncms/feed/data.json?id=117665&start=1527939000000&end=1528544700000&interval=900&skipmissing=1&limitinterval=1

The values Start and End are calculated how exactly ? Are these the relative position in the feed for data ?

I’m open to correction here, I believe it is Unix time, in ms.
So your start time is Sat, 02 Jun 2018 11:30:00 +0000, end is Sat, 09 Jun 2018 11:45:00 +0000
