this script gives a date time stamp  
6-1-2020 tijd: 20:6:11

i want  
06-01-2020 tijd: 20:06:11 (extra 0 before day, month, hour etc.)  
is this possible?

var today = new Date();  
var date = today.getDate() +'-'+(today.getMonth()+1) +'-'+ today.getFullYear();  
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();  
msg.dateTime = date+' tijd: '+time;  
return msg;

You can use `padStart(2, '0')`

> **[String.prototype.padStart()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart)**
>
> The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length.

Take the [moment node](https://flows.nodered.org/node/node-red-contrib-moment), in the output string you can make the output as you want.
