I like your suggested keywords! I think that "AFTER" + "WITHIN" sound 
the most natural. We could completely give up the LSN keyword for now. 
The final command could look something like:

BEGIN AFTER ‘0/303EC60’ WITHIN '5 seconds';
or
BEGIN AFTER ‘0/303EC60’ WITHIN 5000;

I'd like to hear others' opinions on the syntax as well.
