General
1

Hi, how can I add some additional info in a timestamp and function node.

For example:
Klick on Inject: the current timestamp+variables or text from a functions node should be displayed.

output should be:
1575892712962Test

1575892712962 = Timestamp
Test = Variable from function node

[{"id":"2816f926.bcce66","type":"tab","label":"Flow 2","disabled":false,"info":""},{"id":"cac0c772.fefe38","type":"inject","z":"2816f926.bcce66","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":200,"y":180,"wires":[["fad19de.f99af6"]]},{"id":"fad19de.f99af6","type":"function","z":"2816f926.bcce66","name":"","func":"msg = msg && 'Test';\n\nreturn msg;","outputs":1,"noerr":0,"x":380,"y":180,"wires":[["7e1f6e02.470fc"]]},{"id":"7e1f6e02.470fc","type":"debug","z":"2816f926.bcce66","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":550,"y":180,"wires":[]}]

Many Thanks

First off msg muse be an object. You have probabluy noticed running your flow gets a

"Function tried to send a message of type string"

message so you should be using msg.payload instead of msg.

You will run into another problem, but you should be able to figure it out by doing some googling or reading about javascript
