Convert Seconds to Hours, Minutes & Seconds

#1

Node Red 0.19.5 on Raspberry Pi

For display purposes on the dashboard I want to display time remaining in Hours, Minutes & Seconds.

I assume this is a common task to complete, but I have found very little on the best way to do it. Yes there are examples on how to do this in a Function node, but I would have assumed there was a built in Function node for this common task. Am I missing something very obvious?

I did find the convert-seconds Node, but I thought it was strange that such a common task wasn't already available as a Node in the Palette manager. Am I missing something here?

I ended up trying to install the convert-seconds Node, but I can't see it in my Node-Red.

I am still very much learning Node-Red and just starting to understand some of the basic concepts, so any assistance would be greatly appreciated.

If you want to do this easily, the node-red-contrib-moment node lets you format date/time in lots of ways and also lets you deal with timezone differences.

Thanks for the suggestion, however I am dealing with just a period of time from a countdown timer that is not related to a particular time and date. I don't believe the suggested node can help with this situation.

Which node are you using that is generating remaining time in Secs ?

Maybe post your flow ?

I have some code here (below) that was provided to me by another member that allows me to display a countdown from the MyTimeout Node on the Dashboard - here it is if you like

See how you go with that

Just noticed that you do not need the Switch node any longer (the author had a bug previously that this worked around)

You can drop both of them and just put the output of the MyTimeout Node direct to the Dashboard

You can use node-red-contrib-moment if you multiply the seconds by 1000 first (to turn it into msec), like this for example
