[egenix-users] mx.DateTime.now()accuracy

[egenix at jf-gosset.com]

I don't have a compiler installed (I used the binary installer). 
I will install one if you want a feedback, otherwise I think that I can, actually, live with 2.0.3 version.

Thank's a lot for your rapid answer and your explanations.
