Problem sending Date between web services

[HHDirecto . Net]

I have an axis 1.4 webservice,
when My .net client send 1978-12-11T10:30:13 , in java code of web service I do a System.out.println and I get Mon Dec 11 11:30:13 CET 1978. Always 1 hour more.
And when my axis webservice  println I get 2006-08-30 02:11:12.0, It send webservice response as 2006-08-30T 00:11:12.000Z , 2 hours less, and sometimes one hour less.

Do you know the problem?

Thanks
