It's when the index was created, it's unix epoch time.

I tried to use this website ([Online Conversion - Unix time conversion](http://www.onlineconversion.com/unix_time.htm))  
to convert but the result isn't correct.

"creation\_date": "1425631497164" ==\> Wed, 19 Jun 47146 13:12:44 GMT  
\<=== It's wrong!!

Can you recommend which converter or how to?

The creation date is given with millisecond precision. Take away the last 3  
digits and you converter gives Fri, 06 Mar 2015 08:44:57 GMT for 1425631497.

Hi All,

I also require the indexing time to be returned by ES, but when i am firing the query like curl -XGET '[http://192.168.0.179:9200/16-04-2015-index/\_settings](http://192.168.0.179:9200/16-04-2015-index/_settings)'

I am not able to get the index\_creation time and getting the response as : {"16-04-2015-index":{"settings":{"index":{"uuid":"rHmX564PSnuI8cye4GxA1g","number\_of\_replicas":"0","number\_of\_shards":"5","version":{"created":"1030099"}}}}}

Please let me know how i can get the index creation time for the same.

~Prashant

Prashant,

What version of Elasticsearch are you using?

The index creation date added to the index settings API in version 1.4.0  
and will only show for indices created with that version or later  
(see [Store index creation time in index metadata by colings86 · Pull Request #7218 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/pull/7218)).
