Sure.  If all I ever wanted was a simple calculation like that, that'd
work fine, but this was just the simplest test I could come up with, not
the actual use case.  It's fairly common that I want a rule to return a
datetime.

I definitely *could* rewrite a bunch of code to always use timestamps +
timezones, I'm just exploring whether I can avoid that.

Sincerely,
Jeffrey
