I am trying to visualize my data and it's frequency changes in milli seconds.
Can anyone tell me how to deal with this problem?

Why does it show an error?

Mapping is the process of defining how a document, and the fields it contains, are stored and indexed. Date fields are mapped with the Date type. The error is displayed because a field value of -764144999882 is not a valid value when using epoch_millis format.

Thanks for getting back
When i convert this epoch i.e. 764144999882
it comes out to be 1994 11:59:59.882 this. This nowhere even close to time_stamp field I am using in my dataset.
Can you tell me how can i fix this issue?
