Hi,

The timestamp in the log is : `26/Jul/2017:00:00:00`

I defined a pattern: `HTTPDATE %{MONTHDAY}/%{MONTH}/%{YEAR}:%{TIME}`

In the grok I have it : `%{HTTPDATE:timestamp}`

And this is the filter I do:

```
        date {
              match => ["timestamp" , "dd/MMM/YYYY:HH:mm:ss"]
        }

```

The results in output:

```
  "timestamp" => "26/Jul/2017:00:00:00",

  "@timestamp" => 2017-07-25T21:00:00.000Z,

```

**Why isn't it the same?** Any idea?

Thanks  
Sharon.

`timestamp` is local time and `@timestamp` is UTC.
