(Problem) ELK + Amazon S3 + Apache Access Logs

Hi friends, I'm implementing an ELK with apache access logs stores on Amazon S3, but I have a problem when I try to view the graph on Kibana, the dates in the graph doesn't coincide with the dates in logs files. Here a screenshot:

I used these documentation:
How To Install Elasticsearch, Logstash, and Kibana (ELK Stack) on Ubuntu 14.04 - Digital Ocean

Logstash Configuration examples

And this discussion:
Error with S3 input

This is my logstash configuration file:

input {
  s3 {
    bucket => "my-bucket-name"
    delete => false
    interval => 60 # seconds
    prefix => "access/"
    region => "us-east-1"
    type => "apache_access"
    codec => plain {
                    charset => "ISO-8859-1"
            }
    secret_access_key => "my-secret-access-key"
    access_key_id => "my-secret-access-id"
    sincedb_path => "/mnt/apache/log_sincedb"
    backup_to_dir => "/mnt/apache/backup"
    use_ssl => true
    temporary_directory=>"/mnt/tmp/logstash"
  }
}

filter {
  if [path] =~ "access" {
    mutate { replace => { "type" => "apache_access" } }
    grok {
      match => { "message" => "%{COMBINEDAPACHELOG}" }
    }
  }
  date {
    match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
  }
}

output {
  elasticsearch {
    hosts => ["localhost:9200"]
  }
  stdout { codec => rubydebug }
}

I don't know if I have an error with the index pattern on Kibana or if I have an error in mi Logstash configuration file. I would be very grateful if you help me.

(Sorry for my bad english).

You aren't grokking the events and extracting that timestamp to run via the date filter, so start there.

Thank's warkom, How I do it?
