Thanks for a positive feedback. Current design passes instrument time
as global variable from planner to executor. To get it in core we need
to add a field to the planner for that, which I don't think is too
difficult. Anyway I still like its way as it doesn't need any change
in core; free for anyone to use, even in the older versions.
