This sounds like a bug on the platform you are using or
with the compiler.

Which version of egenix-mx-base are you using ? Testing with
the latest snapshot of egenix-mx-base, I don't get this output:

 >>> import mx.DateTime
 >>> date = mx.DateTime.DateTime(2005, 1, 2, 12, 42, 27.64)
 >>> print date
2005-01-02 12:42:27.64
 >>> print date + 0
2005-01-02 12:42:27.64
 >>> print date - 0
2005-01-02 12:42:27.64
