  Log:
    time.c (time_timespec): fix tv_nsec overflow
    
    test/ruby/test_float.rb (test_sleep_with_Float) causes tv_nsec
    to hit 1000000000 exactly.  This bug is currently hidden from
    our test by the platform-dependent native_cond_timeout
    functions, but a future native_cond_timedwait implementation may
    prefer relative timeouts to match ConditionVariable#wait
    semantics more closely.
    [Bug #10144]
