I have some long delays in a flow and I wanted to know how much time is remaining in them (one is 30 secs - the other is 5 minutes) when I'm sitting around debugging it.
Using Blockly, I've come up with this combination of a Blockly (or JS function) node and a standard delay node
The Blockly node defaults to counting down in 10 sec intervals from 60 seconds (these seemed like a reasonable defaults for a long running delay) but you can override the number of steps and the overall delay by inserting msg.steps and/or msg.delay (which is in seconds not milliseconds) into the flow along with the actual real msg
The flow here contains both the Blocky version and a copy/paste of the JS code it generates to be used in a function node if you want to use it that way
