4727	thread_time.hpp get_system_time depends on BOOST_DATE_TIME_HAS_HIGH_PRECISION_CLOCK being defined	nstewart@…	Anthony Williams	"Came across this issue while cross-compiling for Android.

The implementation of boost::get_system_time depends on microsec_clock<system_time>, which does not exist unless BOOST_DATE_TIME_HAS_HIGH_PRECISION_CLOCK is defined.

The attached patch takes a similar approach to:
