Yes, I discovered work around few days ago. 
I posted the error here, because I think that this error indicates,
that something wrong with design.

I think that date_time library should define local_microsec_clock,
not in terms of microsec_clock, but using an other class that is 
aware of time zone. 

Why is microsec_clock class not aware of time zones?
