 Tested this
 https://github.com/boostorg/thread/commit/8f5de1d7c34ff7248261874f273498a622bf76d4

 on ARM/Linux.
 Problem is still the same:
 boost::this_thread::sleep_for() hangs if system clock is rolled back,
 returns if clock rolled forward again.
 Now a question:
 Is it enough to #define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC in
 my code or does it have to be defined when building boost ?
 In the latter case, where to put this #define ?

 Information:
 With boost 1.59.0 on i386/Ubuntu 12.04 the behavior of
 boost::this_thread::sleep_for()is correct, no impact when rolling back the
 system clock.
 The problem seems specific to ARM.
