Can we have a wobble with two Date.TimeNow nodes?
More makes it more exciting 
Two date time?
Why would two make a difference?

You can build a custom definition which returns DateTime.Now() in design script, and call that function as desired. Put a time sync in (perhaps via Python) if you need more of a gap than a few milliseconds and I think you’ll get the kind of results you want.
Ow wow, like in imperative?
No need for imperative.
Just a definition along the lines of this (not at my PC so pardon any typing issues as phone web browsers don’t have any error handling):
def rightNow(trigger: var)
{
return = DateTime.Now();
};
