i want delete of the first twelve characters received from a UDP network message?  
in the beginning of the network message, the date and time are indicated, I do not want forward this information.  
I just want to recover the information that is after the date and time.

example UDP network message received:  
20\_06\_20 12:30:02 alarm triggering input 1

I wish to simply forward or use:  
alarm trigger input 1

thanks for your return

You can add a function node that calls `substr`

```auto
msg.payload = msg.payload.substr(18);
return msg;

```

Proof....

Probably also possible in a change node with JSONata
