This means that we'll print HH:MM:01.999, which is quite far from either value.

WebBoth tv_sec and tv_usec are significant in determining the duration of a timer. Timers will never expire before the requested time, but may expire some (short) time afterward, which depends on the system timer resolution and on the system load; see time(7). (But see BUGS below.) Upon expiration, a signal will be generated and the timer reset.
