Im using [Elasticsearch.Net](http://Elasticsearch.Net) and I would like the server to supply a value to a field when I create a document in a index. specifically time. I want the client to supply a time value (generated on the client), and I want the server to add/supply a time value to another field for its time. The purpose is to assess if a client (multiple clients really) has a very poor clock. I'm at a bit of loss on how to do this, or if this already exists in some fashion Thanks, Alex ---

You can do this on the client side, but having a timestamp automatically added by Elasticsearch is not possible. ---
