Hi,

In 5.x we used to fetch @timestamp as epoch using docvalue\_field in the query. We have upgraded to 6.x from 5.x and seeing that @timestamp is in text format even though we use docvalues\_field in 6.x. Could you help to fetch timestamp in epoch format.

Below is the output of a query from both the versions

In 5.x it is numeric:  
"\_source": {  
"event\_id": "f31f32a2796dac9f9e795347516afe03e57bd843",  
"event\_timestamp": "2018-02-12T02:50:57.277482+00:00"  
},  
"fields": {  
"event\_timestamp": [  
1518403857277  
]  
},

In 6.x it is textual:  
"\_source": {  
"event\_id": "f31f32a2796dac9f9e795347516afe03e57bd843",  
"event\_timestamp": "2018-02-12T02:50:57.277482+00:00"  
},  
"fields": {  
"event\_timestamp": [  
"2018-02-06T13:35:35.225Z"  
]  
}
