We have our documents indexed in Elastic search. Each of these documents has date field captured without the timezone (By default, we are capturing the date in IST timezone, without the timezone). For obvious reasons, this is not right.
We are planning to capture date in UTC timezone and migrate all existing documents to capture the date in UTC timezone. After going through a couple of documents, I did not get any definitive guide to do this.
Need some expert opinion on how to solve this issue. Really appreciate every opinion.
