Intel 7.0 Compiler and date_time library

First of all I would like to thank everybody who responded on my 
previous post.

The real showstopper for me at the moment is date_time library. I did 
a small test -- compiled and run days_till_new_year.cpp against boost 
1.29 (patched to not complain about __ICL 700) and current snapshot of 
boost CVS. Here is what I've got (cpp was renamed to test.cpp for 
short):

----------------------------------------------

As you can see both versions are broken. What I don't understand is 
how come that boost regression tests are Ok? Am I using wrong version 
of Intel Compiler, or am I missing some magic flags to compiler?

I will send this report to Intel tech support; however I would 
appreciate if someone will verify these results, and contact Intel on 
behalf of Boost community.
