I'll throw my hat into this.
Option:
text input node. Set to input date format.
Sorry. Just saw you can't do that.
Send that through a node that will convert that to a timestamp value.
Use a change node to set flow context of this value. (Say flow.wait_until)
Next part:
inject node spitting out a timestamp every.... second. Given you want second accuracy.
That goes into a switch node. This is configured to say:
if (msg.payload == flow.get(wait_until)
So only when the timestamp matches the flow context does it let the packet through.
You could maybe /1000 to make it real seconds, as I think the millisecond resolution is just a bit too much to ask.
Ok, not worded the best, but do you understand the gist of what I am saying?
I think only one extra node is required. I think it is the moment node.
Sorry I can't name it exactly.
But anyway, that's my idea/thought/suggestion.
Idea in flow format:
Needed to do:
The inject node needs to be set to inject every second.

You may need to tweak the moment node.
But I hope you get the idea.
