Date data type and time for kibana

Elastic Stack Kibana
5

ok so if I understand well I need to create another index with the following script:

    
POST _reindex
{
  "source": {
    "index": "my-index-000001",
    "TIME": {
      "type": "string"
    }
  },
  "dest": {
    "index": "my-new-index-000001",
     "TIME": {
      "type": "string"
     }
  }
}

but instead of doing it is not easier to do as following?
```

consumer = KafkaConsumer(
'stream',
bootstrap_servers=['localhost:9092'],
auto_offset_reset='earliest',
enable_auto_commit=True,
group_id='my-group-id',
value_deserializer=lambda x: loads(x.decode('utf-8')))
i=0
indexVal="provaTempi"
es=Elasticsearch([{'host': 'localhost', 'port': 9200}]) 
for event in consumer:
   dt_string=event.value['DATE']+" "+event.value['TIME'] 
   print(dt_string)  
   format1='%m/%d/%y %H:%M:%S'
   data=event.value
   timestampRow=datetime.datetime.strptime(dt_string,format1)
   event_data = {'START TIME': data['START TIME'], 'DATE': data['DATE'], 'TIME': data['TIME'], 'TIMESTAMP': timestampRow, }
   i=i+1
   res=es.index(index=indexVal,id=i, body=event.data)


So according to this script I manage to insert date type into kibana. After creating the patterns on kibana I manage to see the date datatype for TIMESTAMP. With the same pattern of converting date+time I do the same for single like START TIME value as ok?
Thanks
