Hi ,

Is there any way to modify date format on logstash filter file.

I am using the current once

date {  
match =\> ["submit\_time\_unix", "UNIX"]  
target =\> "submit\_time\_unix"  
}

and the o/p is "June 22nd 2016, 01:54:30.000" and but I want it should be "2016-06-22"

"June 22nd 2016, 01:54:30.000" is how Kibana formats it, and I believe that format is configurable. If you look at the actual document contents you'll see that it's ISO8601.
