How to change between 12 and 24 hour time display?

Hello, is there a way to change these history messages into 12 hour (AM/PM) time format?

I've searched for a solution to this and see a lot of people struggling to input time, but I am just trying to display time in 12 hour format. I live in USA and my browser and computer are all set to 12 hour format, but I can't find any setting for this in Node-RED.



It would help to know what node you are using, but since that is a status message I would assume that this is something that is controled by te node itself. You might want to ask the node's author on the node's GitHub page.

The node is just a simple "call service" that comes from the default set.

Could you export your flow and attach it to a response?

When you say it is part of the default set, how did you install Node-RED?

That looks to me like a Home Assistant node - not one of the default palette.

Have a look at the help for the node as to who authored it and the options for it.


I installed Node-RED from within Home Assistant.
Here is a 38 second recording of me making a sequence with the issue:
Below is the code of what I created in the clip above.

[{"id":"bf47a926.e6f82","type":"api-call-service","z":"2014399e.c57456","name":"","server":"4188bc1a.bd4c54","version":1,"debugenabled":false,"service_domain":"switch","service":"toggle","entityId":"switch.office_lamp_2","data":"","dataType":"json","mergecontext":"","output_location":"","output_location_type":"none","mustacheAltTags":false,"x":480,"y":360,"wires":[[]]},{"id":"4188bc1a.bd4c54","type":"server","name":"Home Assistant","addon":true}]

Yep - so drap one of these nodes onto the palette and then go over to the help/doc on the right hand side and see what the usage is and who the author is.

These are custom nodes that the Home Assistant implementation of NR includes - not standard nodes



Sorry I figured they were default because they came with the installation in HA and I didn't add them.

The link above explains a little more about the call service node but doesn't explain anything about contorting the time format. Is there a different place I should ask this question?

I'm little confused why something so basic isn't controlled by a simple toggle switch or checkbox somewhere.

You are probably best off opening a feature request on their github page:

Options for formatting the node status is not something that you will find on many nodes if any as that status is really just a nice to have features for quick glance information while developing.
Design wise the paradigm here is that the flow editor is not a dashboard and its also good practice not to overload a nodes ui with too many options.
For showing information exactly like you want it the information is probably also included as a timestamp in the nodes output messages as a property and you could format that output yourself to show it in the nodered dashboard in your wanted format.

No problem - you are not actually using the default HA nodes i believe you are using the Community Websocket Add on (may be wrong here) - if you look on the link i provided there is a link to their github page and you can open an issue on there
