In mxDateTime 3.x we're using a more direct way of getting the
current time which is faster. Apparently, on Windows this doesn't
provide the full accuracy anymore.

We'll add a fix for this to the next eGenix mx Base release.

As work-around you can comment out the following line in egenix_mx_base.py
of the distribution to have mxDateTime use the 2.x strategy again:

                 #define_macros=[('USE_FAST_GETCURRENTTIME', None)],

Some more context:

    mx_Extension('mx.DateTime.mxDateTime.mxDateTime',
                 ['mx/DateTime/mxDateTime/mxDateTime.c'],
                 # If mxDateTime doesn't compile, try removing the next line.
                 #define_macros=[('USE_FAST_GETCURRENTTIME', None)],
                 #
                 include_dirs=['mx/DateTime/mxDateTime'],
                 optional_libraries=_mxDateTime_optional_libraries,
                 ),

You'll then have to recompile the package using

python setup.py bdist_msi

and install the generated MSI file.

Thanks,
