In case of multiple events in one message we have ordering precedents 
for that.  If you manage to send to separate messages with the same
time stamp then I agree, it might fail due to ambiguity.  But this is
not the situation where we have a starting time stamp, and an ending
time set by the starting time stamp.

Legally, I think we have to assume that the message was sent *exactly*
to the resolution of the timestamp (e.g. subseconds on down .00000...).
This isn't the real word time of sending, but it is the legal world time
of sending.  It seems common-sense-ish to me, but I'll agree that there's 
no precedent on that.  And I think the "within" langauge applies to being 
within that legal (not actual) window.

What would be interesting would be if two different people set up cron
jobs to do something contradictory (e.g. where order mattered) with
identical times to the resolution of the timestamp.  There, neither 
person would have performed an ambiguous action, but together they
would have.
