Summary:                    Registration uses hwclock and sysclock to retrieve
time
Description: 
It looks like different areas of the SIP registration code retrieve the
date/time differently. Under *most* conditions the time is pulled from the
sysclock, however, under some rare conditions the time appears to be pulled
from the hwclock.

My system had the hardware clock set 4 hours ahead of the sysclock (it's a
new system and I had never ran /sbin/hwclock --systohc).

Once every day or so, my service would go out, and "sip show registry"
would report a registration time in the future.  Asterisk was showing me as
connected with a registration time 4 hours into the future, but my provider
was timing me out.

I tried the following settings (with no luck)
sip.conf:
[general]
...
registerattempts=0
registertimeout=60
defaultexpiry=120

Granted it's my fault that I did not set the hwclock, but I think Asterisk
should also be more consistent on how it pulls the date/time -- hwclock or
sysclock, one or the other.

Asterisk is very consistent on how it pulls the time -- it's always the
sysclock, never the hwclock.  Presumably, you have some other process that
is setting the sysclock to the hwclock.
