You can generate such date Sting with a [SimpleDateFormat](https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html), store it in the Session in an [exec(function) block](https://gatling.io/docs/current/general/scenario/#exec) and inject it in your request body with [Gatling EL](https://gatling.io/docs/current/session/expression_el/).
