Timestamp in Druidbeam.builder

Hi All,

I was going through the scala doc of Druidbeams Object ( http://static.druid.io/tranquility/api/latest/#com.metamx.tranquility.druid.DruidBeams$ )

val sender = DruidBeams

.builder[Map[String, Any]](eventMap => new DateTime(eventMap(“timestamp”)))

I had following doubts :

-What does the time we specify inside Builder mean ?

  • if I always pass DateTime.now inside Builder instead of the timestamp from my event , what effect will it have on the Druidbeam?

Thank you.
