[pulseaudio-discuss] snd_pcm_htimestamp error

[golden]

  Thanks, I just found the problem, when building alsa-lib,
  the HAVE_CLOCK_GETTIME is not defined in config.h,
  so mononic time is not supported in alsa-lib, after changed system date,
  snd_pcm_htimestamp always return the time from 1970.
