How to add a random value for a timestamp to the header

Hello to everyone.

I’m pretty new in the using of Gatling and now i’m confused with a question if it possible to add a random value of timestamp to the header that for every user that value would be different?
For an instance:

Введите код...val headers_49 = Map(

 "Accept" -> "application/json, text/plain, */*",
 "Accept-Encoding" -> "gzip, deflate, br",
 "Accept-Language" -> "ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7",
 "Content-Length" -> "0",
 "Content-Type" -> "application/json;charset=UTF-8",
 "client-capabilities" -> "authentication=13.19.2",
 "client-operation-id" -> "1576756499120"
)

Thank you in advance.
