Timestamp to current date and time?

Hi all… what would the code be that goes into a function node to take a timestamp and output the date and time in the normal date and time format?

You can write down a function, can take a look for it I have it somewhere in my code however the more easy is use a node called moment, is what I’m using most frequently.

I’m using this on several ways and make a global set of the formatted date, then on any function u can directly recall the global variable and get the date formatted directly as u wish.

Hey…brilliant guys… thanks. Both those suggestions work. I have gone with the moment node as I managed to get it to display local time - but I did like the json cheat…:slight_smile:

Yep Moment.JS is brilliant. The other day i decided to write function to get the date and time into a reasonable format so i could pipe it out inline to a log file with some status info.

After spending 4 hours cruising around (learning a LOT), decided it was a waste of time and far smarter to do it in the moment node - took all of 10 minutes to get it up and running

I'm amazed that some brilliant chap wrote the moment node to help in situations like this :wink:

To be fair though, Moment.js, while excellent, is BIG. You should avoid it if resources are an issue. But it is comprehensive and does cover pretty much every edge-case for date/time handling.

Yep he is brilliant - should give up his day job !! :grinning::rofl:

I run my Node-red on a Ubuntu VM so resources are not really an issue for me

Haha, sadly his day job pays rather too well to give up right now :wink: A few years yet until I can do a "Pete Scargill" and retire :smile:

If you want a lightweight solution, try node-red-contrib-simpletime.

Question..
With this cheat...how can I get the payload/message to also be included in the timestamp?

Example I have a GPIO pin that goes to a change node. It changes a 0 or 1 to a message and then off to an email node. I would like to have it include a timestamp and the message.

Thanks!

payload &" "& $now(), for example.

Thank you so much! I am new to this and trying to teach myself. I understand some complex things..but get tripped on the simple stuff from time to time.

How can you include a timestamp into existing JSON data used by HomeAssistant?

Thanks,
Jon

Did you get an answer for this? "want_timestamp_here"?

The easiest way is to use the payload in there. So you can use the timestamp inject node then change that to whatever format you want using a change node. Finally, your json would look like this:
{
"name": "Automated Backup {{payload}}"
}

This simple solution results with string like:
"2019-07-26T09:00:12.214Z"

The string does not fit the current time zone and not quite human readable.
I tried to use $now().toLocaleString(), however now() is not JS function.

How to format $now() to human readable and local timezone format?
The Linux knows the timezone, so I guess Node-Red knows it too.

Any of outputs in the topic above (https://github.com/nodejs/node/issues/8500) is considered as human readable :slight_smile:
Thank you.

@igrowing Have you installed and tried node-red-contrib-momentyet (as several people in this thread have suggested)?

@zenofmud Seems I took this warning too seriously.
Is now() function of Node-Red or JS?

Installed 'simpletime'. Tried to show the datetime in Text UI node as:
{{msg.payload.mydate}} {{msg.payload.mytimes}}
Resulting nothing.

The $now function that was used in the original reply of this topic is a JSONata function as used in the 'expression' type of the Change node.

JavaScript has its own Date object and all of its associated functions. You can learn about it here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date
You would use this in the Function node.
