Subject: [musl] Prefer monotonic clock for DNS lookup timeouts
Date: Thu, 1 Dec 2022 12:24:47 +0100	[thread overview]
Message-ID: <> (raw)


while looking for a reason for a failed DNS resolve I noticed that
the mtime function which is used to calculate and decide on the timeout 
uses the wall clock instead of a monotonic clock:

static unsigned long mtime()
	struct timespec ts;
	clock_gettime(CLOCK_REALTIME, &ts);
	return (unsigned long)ts.tv_sec * 1000
		+ ts.tv_nsec / 1000000;

Is this a bug or intentional?
