Hi, please dont mass tag members. We will see (and respond) if we can help, when we get a moment.

Speaking of which, you can use `$moment` in JSONata

See here: [Formatting times & dates with moment.js examples](https://discourse.nodered.org/t/formatting-times-dates-with-moment-js-examples/29553)

Have you done a google search? Try ‘JavaScript date formatting’

Do you realize you send a msg to the text node three different ways in your flow??

Why? Just pass your message through a change node to append a formatted date...

JSONata: `payload & " " & $moment().format("YYYY-MM-DD HH:mm")`
