[atlas] Streaming API, endTime parameter is ignored

Hello everybody, I am an Italian student and I am working with the RIPE Atlas Streaming API. I am trying to replay events that have happened in the past, so I am using the optional parameter endTime in the code below. Now, the stream starts at the specified time but it never ends. Am I doing anything wrong? Is this a bug? var socket = io(“https://atlas-stream.ripe.net <https://atlas-stream.ripe.net/>:443” , {path: “/stream/socket.io <http://socket.io/>”}); startTime = 1486256400 //05-02-17 h: 01:00GMT endTime = 1486258200 //05-02-17 h: 01:30GMT socket.emit(“atlas_subscribe”, {stream_type: “result”, startTime: startTime, endTime: endTime, msm: 1962548}); Best, Roberto Nunziato
