9880	[windows] boost::condition_variable.timed_wait() exception if system time < 1970	anonymous	viboes	"Os: any windows. 
Set system time < 01.01.1970, for example 01.01.1950.

Any call to boost::condition_variable.timed_wait() with relative(!) time throw exception because boost try get system time in posix format.

How to fix: 
boost\thread\win32\thread_data.hpp, line 179 (boost 1.55.0). In constructor 

{{{
            timeout(uintmax_t milliseconds_):
                start(win32::GetTickCount64()),
                milliseconds(milliseconds_),
                relative(true),
                abs_time(boost::get_system_time())
            {}
}}}

we set ""relative(true)"" and there for not need to set variable ""abs_time"". Must be:

{{{
            timeout(uintmax_t milliseconds_):
                start(win32::GetTickCount64()),
                milliseconds(milliseconds_),
                relative(true)
            {}
}}}
