Date time format

Hi,

I am new to gatling and I want to pass time parameter in json post Body in gatling .
In Jmeter I am good by using below parameter:
${__time(yyyy-MM-dd’T’hh:mm:ss}

Please suggest me , how can we pass custom time format for below post pody in gatling.

post Body :
{
“updateTimeStamp”: “2020-04-21T09:22:20”

}

You can generate such date Sting with a SimpleDateFormat, store it in the Session in an exec(function) block and inject it in your request body with Gatling EL.
