I cannot find this to be true. >From what I can make of the code, clock_settime() ends up calling do_sys_settimeofday() for CLOCK_REALTIME (and the other clocks). It is, however, not treating relative/abs timers any differently. Both get converted to an absolute expiration time when set. If POSIX mandates that we keep relative timers unchanged when we change the underlying clock, we'd have to iterate all pending timers and reset them. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
