You did more than *just* that, since doing just that much works fine.
You're going to have to remember what else you did.

Indeed, there is no persistent.TimeStamp class in ZODB 3.2.3.  This
*suggests* you perhaps also installed an alpha or beta version of ZODB 3.3,
and left that installed then tried to install 3.2.3 on top of it.

But it's impossible to guess on this end.  For example, maybe you forced
your PYTHONPATH to an inappropriate value, etc.  With some luck, though, you
can remember what you did.
