+Installing This Package
+=======================
+
+Prerequisites
+-------------
+
+The installation steps below assume that you have the cool new 'setuptools'
+package installed in your Python. Here is where to get it:
+
+ $ wget http://peak.telecommunity.com/dist/ez_setup.py
+ $ /path/to/your/python ez_setup.py # req. write access to 'site-packages'
+
+ - Docs for EasyInstall:
+ http://peak.telecommunity.com/DevCenter/EasyInstall
+
+ - Docs for setuptools:
+ http://peak.telecommunity.com/DevCenter/setuptools
+
+ - Docs for eggs:
+ http://peak.telecommunity.com/DevCenter/PythonEggs
+
+
+Installing a Development Checkout
+---------------------------------
+
+Check out the package from subversion:
+
+ $ svn co svn+ssh://svn.zope.org/repos/main/zope.timestamp/trunk \
+ src/zope.timestamp
+ $ cd src/zope.timestamp
+
+Install it as a "devlopment egg":
+
+ $ /path/to/your/python setup.py devel
+
+Running the Tests
+-----------------
+
+Eventually, you should be able to type:
+
+ $ /path/to/your/python setup.py test
+
+and have it run the tests. Today, the workaround is run the tests
+from the checkout's 'zope' directory:
+
+ $ /path/to/your/python tests.py
+ Running:
+ .............
+ Ran 5 tests with 0 failures and 0 errors in 0.094 seconds.
+
+Installing a Source Distribution
+--------------------------------
+
+You can also install it from a source distribution:
+
+ $ /path/to/easy_install --find-links="...." -eb src zope-timestamp
+ $ cd src/zope.weakset
+ $ /path/to/your/python setup.py devel
+
+
+Installing a Binary Egg
+-----------------------
+
+Install the package as a "binary egg" (which also installs its "hard"
+dependencies):
+
+ $ /path/to/easy_install --find-links="...." zope-timestamp
+
+
Added: zope.timestamp/setup.py

+"""Zope Object Database: object database and persistence
+
+The Zope Object Database provides an object-oriented database for
+Python that provides a high-degree of transparency. Applications can
+take advantage of object database features with few, if any, changes

+ # TimeStamps into a second, it's not good at roundtrip accuracy.
+ # For example, 1 second is stored as int(2**32/60) == 71582788.
+ # Converting back gives 71582788*60.0/2**32 == 0.9999999962747097.
+ # In general, we can lose up to 0.999... to truncation during
+ # storing, creating an absolute error up to about 1*60.0/2**32 ==
+ # 0.000000014 on the seconds value we get back. This is so even
+ # when we have an exact integral second value going in (as we
+ # do in this test), so we can't expect equality in any comparison
+ # involving seconds. Minutes (etc) are stored exactly, so we
+ # can expect equality for those.
