Everyone,
  I love that my proposal for %T in the prompt, triggered some great
conversations.

  This is not instead of that.  That lets me run a query and come back
HOURS later, and know it finished before 7PM like it was supposed to!

  This feature is simple.  We forget to set \timing on...
We run a query, and we WONDER... how long did  that take.

  This, too, should be a trivial problem (the code will tell).

  I am proposing this to get feedback (I don't have a final design in mind,
but I will start by reviewing when and how ROW_COUNT gets set, and what
\timing reports).

  Next up, as I learn (and make mistakes), this toughens me up...

  I am not sure the name is right, but I would like to report it in the
same (ms) units as \timing, since there is an implicit relationship in what
they are doing.

  I think like ROW_COUNT, it should not change because of internal commands.
So, you guys +1 this thing, give additional comments.  When the feedback
settles, I commit to making it happen.

Thanks, Kirk
