Multiple created_at fields in JSON output. Any way to limit this?

[ESMTools]

Hello,

We are using Splunk to parse through our twitter feed that looks at key words but are having issues parsing out the the timestamp since there are many created_at fields in the JSON output. Is there a way to limit this to only show the current timestamp of when the tweet was sent? If not which timestamp should we care about?

The API responds with structured data… if you’re consuming the data into a hashmap or similar structure, it should be obvious which objects the various fields belong to… There’s only one created_at field directly attached to a core tweet object, for example.
