In 1.52 sleep_for behaves like normal sleep [system_clock, which introduces problems witch changing time while sleeping] if in new thread. How to reproduce: Compile and run the test. Change time [date -s 10:00:00]. Main thread will exit sleep_for after 10 seconds. Boost::thread will end after some other time. In correct situation [ex. boost 1.51] they should end simultaneously. I think it's introduced in revision 80450. Example program demonstrating this behavior is attached." Bugs closed Boost 1.60.0 thread Boost 1.52.0 Regression fixed
