Hi PulseAudio forks,

    snd_pcm_htimestamp is unstable after change the date time of OS by 
using "date -s xxx-xxx-xx",
    It is very strange that the time value get from snd_pcm_htimestamp 
is always 1420588802151082308

    and here is what I get when cat the alsa infomation:

     uid=0 gid=0 at nutshell:/ # cat /proc/asound/card0/pcm0p/sub0/status
     state: RUNNING
     owner_pid   : 1339
     trigger_time: 1420591411.800808521
     tstamp      : 1420591457.486751372
     delay       : 5040
     avail       : 3152
     avail_max   : 0
     -----
     hw_ptr      : 2193408
     appl_ptr    : 2198448

     Does anyone met this problem before ?

     Thanks!



BR,
Lixin
