interprocess_condition::timed_wait() requires time as universal_time, not local_time

I'm used to using boost::posix_time::microsec_clock::local_time() or std::chrono::steady_clock::now() as my time base for most boost timed wait functionality. However, it seems that interprocess_condition::timed_wait() returns false immediately for me when I have a time 1 second in the future (I am in UTC-7 time zone). Things start to work fine if I either adjust my system time to UTC+0 or update the code to instead use boost::posix_time::microsec_clock::universal_time() as my time base.

If this is instead a misunderstanding on my end, I would like to see the documentation updated to clarify this.

The one area I have played around with where the type of clock used didn't seem to matter was with boost::asio::io_service::run_until() where I use an offset from std::chrono::steady_clock::now(). Since this is all a part of boost, I assumed I could just reference this code for interprocess code. Now that I'm looking more closely, boost::asio::io_service::run_until() uses const chrono::time_point< Clock, Duration > & abs_time, and interprocess_condition::timed_wait() uses const boost::posix_time::ptime & abs_time.
