Subject: pcm: use CLOCK_REALTIME for non-monotonic ts
X-Git-Tag: v1.0.28~30
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=66f07aa3b77e4013110f7b12640e204d0c15ac8d;p=alsa-lib.git

pcm: use CLOCK_REALTIME for non-monotonic ts

gettimeofday() is the same than clock_gettime(CLOCK_REALTIME)
except for the loss of precision and the double unnecessary
conversion timespec <-> timeval.
