Well, in everyday life, a "duration" is what is between start and end.
Here's the
trivial relation between the notation used in the temporal operators' docs
and
the @nnotated fields in an event:

$x.startTimestamp == @timestamp
$x.endTimestamp == @timestamp + @duration

I think that the operator definitions are clear enough - do you have any
particular problem?
