Easy way of adding only mytimes to a msg

General

I assume that you are adding simpletime just before another node which makes use of mytimes, maybe to construct an array or something?
If so, could you not limit the flow to just the payload & topic downstream AFTER adding hh:mm:ss into the flow structure by creating a new msg object, such as;

var newMsg = { payload: msg.payload,topic:msg.topic };
return newMsg;

or even;

let d = msg.payload;
return {payload:d};
