RE: [boost] reminder about Date/Time formal review

Based on the discussion about this topic here I vote for NO.

I don't care for the internal implementation but the interface
should be relatively stable, which is not the case.

First of all I would like to see a dependency diagram 
like this (dependency != inheritance)

simple_date (Gregorian?, no DST, no LS, ...)
   ^
   |
date_with_dst
   ^
   |
date_with_ls

etc... 

The most effective way (and sufficient for many (most?) applications) is
to have a "floating" date base. That means
simple_date( "now" ) == local_date( "now" ). But for
dates 4 years old (before 1/1/99) you will miss the leap seconds.
If you try it the other way around with TAI as a base you always
have to pay a prize in adding the leap seconds (32? in the moment).
