Data Types Issue 64: IVL center issue
Introduction
[from Charlie]
Usecase -- I am to take insulin from tomorrow until eternity. How should that be converted into a point in time (for displaying on a date sorted list).
It can't be.--GrahameGrieve 21:19, 20 June 2007 (CDT)
This is the usage for which the property center is defined in the abstract - and the abstract spec says that it should be taken to be "not applicable" in the formal constraints -- which seemed wrong to me -- the midpoint of tomorrow and eternity is eternity.

Discussion
But I did beef up the invariants about low, high, width, and center considerably
