[App_rpt-users] RTCM question(s)

I occasionally get a connection lost/connect established almost back to back
on my RTCM at a remote site.  This is on a hardwired IP connection (finally)
with pretty low latency and no significant packet loss in the audio on
either side.

e.g. here is my response rate from a remote ping to my RTCM

Pinging <host ipaddress> [64.16..] with 32 bytes of data:
Reply from 64.16..: bytes=32 time=60ms TTL=52

Ping statistics for 64.16..:
    Packets: Sent = 37, Received = 37, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 57ms, Maximum = 150ms, Average = 87ms

2 questions.  Is there some way to set a time display on the messages on an
RTCM when it  isn't connected to a GPS, I can't tell how long the duration
is between the back to back messages because all I get is  as follows.  

<System Time Not Set>  ERROR! Host response timeout
<System Time Not Set>  Host Connection Lost (Pri) (24.99.5x.xxx)
<System Time Not Set>  Using Primary Voter Host (24.99.5x.xxx)
<System Time Not Set>  Host Connection established (Pri) (24.99.5x.xxx)

This is a single RTCM running in simple radio interface mode.

Can you run an RTCM in simple mode and still connect it to a GPS?  Will that
set it's time locally?

Is there any way to set a parameter to lengthen the timeout timer in either
the voter.conf file or the RTCM configuration?  I'm sure we are only talking
about a few milliseconds difference is all that's needed.

Thanks in advance,
Alan
