[LEAPSECS] Leap smear

[Rob Seaman]

Rather I love the coherent collection of requirements.  Still find it interesting that none of my more "creative" talking points gets under the skin like simply recommending that coherent system engineering best practices be followed.

Usual comment about apparent solar time being a red herring.  Consider the fact that we moved from apparent solar timekeeping to mean solar timekeeping.

We have had all these discussions before.  Signing off for the reception with the Lord Mayor.

Trouble is people get up when it gets light (and thus don't care about what the clocks say), or they get up with their alarm goes off (in which case they don't care if it is light: the boss man says be here by 8:00am).  People care more about there being less light in winter making them depressed than they do about the mean apparent solar time error while they are ingesting their mid-day meal.
