Yeah, but only if the value isn't recalculated shortly later.  Consider
caller computes finish_time = time() + timeout;
...
inside select-wait loop, compute max_delay = finish_time - time();

If the time() value has incremented by 1 second between these two lines
of code, you have a problem with a 1-second timeout...
