Hi

I use logstash to put my IIS log files to elseicsearch. I use my own grok filter:  
"message", "%{TIMESTAMP\_ISO8601:request\_timestamp} %{IP:server\_ip} %{WORD:request\_method} %{URIPATH:request\_uri} %{NOTSPACE:request\_query} %{NUMBER:port} %{NOTSPACE:username} %{IP:client\_ip} %{NOTSPACE:request\_agent} %{NOTSPACE:request\_referer} %{INT:response\_status} %{INT:response\_substatus} %{INT:response\_winstatus} %{INT:response\_timetaken}"

Then I use DSL query to elasticsearch to get the logs where request\_timestamp field is in specified date range, and there are logs from outside the range.  
However if I take range using @timestamp column the results seems to be fine - so In my opinion the problem is with field type.  
I have even defined an index template where my field definitione is:  
"request\_timestamp" : {  
"type" : "date",  
"format" : "yyyy-MM-dd HH:mm:ss"  
}  
but it still does not work (default logstash definitione was text).  
How to solve it? Or even better how to use date from my logs as @timestamp column, which in my specific case is completelly useless.

@waitangi

Have you verified if the timezone of your query matches the timezone of your `request_timestamp` values?

Got it. I added timezone =\> "UTC" to date definition in configuration file, Then I added remove\_field =\> ["request\_timestamp"] and now I have in @timestamp parsed date from the log file and no request\_timestamp column. It suits me fine.  
Thanks davemoore.
