My bad.  I should be clearer about the source of my confusion.

Given two identical string representations of POSIXct objects, can the two
objects represent different times?

Browse[2]> Time
[1] "2012-03-20 00:59:57 NZDT"

Browse[2]> index(DATA.ba[[p]]["2012-03-20 00:59:57","bid"])
[1] "2012-03-20 00:59:57 NZDT"

A reproducible example would be huge at this point.  WHat I need is an
answer to that simple question.  If the answer is  "No" then it is worth
doing the work for a reproducible example.  If "Yes" I need to learn why
and better ways of pasing the objects in and out of matrices and vectors.

Using R version  2.12.1

The zoo documentation (?zoo) does not include a version.  Where can I find
it?
