Driver signing (EV certificate) fails before 9am.

I would be nice to be able to codesign my driver before 9am sometimes, being in Japan that presumably means before midnight GMT. If I try, I get an error "future date" from the Validation section in New Hardware Submission.  Unless it is something I do wrong? I do use " /uselocaltime". 

This is not a new issue, never been able to. Wait until 9am and codesign of the very same binary works fine.
