Custom date format in elasticsearch

[Pranjal_Sett]

Hi,

I am trying to index the data with the data as May 26 2022 17:41:24 . I have given the format in my index template as MMM d Y H:m:s . I have been following this link for formatting http://joda-time.sourceforge.net/api-release/org/joda/time/format/DateTimeFormat.html .

Parsing for this data is happening fine with this mentioned format. After indexing this data I have been seen in Kibana as below:

After Indexing data:
"configuration_date_time": [
"2022-01-03T17:41:24.000Z"
],
So it is coming as 3rd January but actually it is May 26.
Actual data: "configuration_date_time": "May 26 2022 17:41:24",

How come it is converting this May 26 to 3rd Jan. I am confused. Can anyone please help me on this? Where I am missing?
