Server detected a backward timestamp from 1973406 to 0 in file

Question

In my core.log file I'm receiving these error messages;
Server detected a backward timestamp from 1973406 to 0 in file:C:\FMSHOME\applications\livepkgr\streams\_definst_\bbc1
Server detected a backward timestamp from 1973406 to 0 in file:C:\FMSHOME\applications\livepkgr\streams\_definst_\bbc2
Is this an issue caused by the encoder? I'm using a Viewcast Niagara to encode and not the FMLE. These are the only settings I have available.
I'm using all default settings on the FMS 4.5 server. 
Thanks,
Dave

Answer 1

I'm checking again with Viewcast support .I don't see how I can check whether ATC is enabled on the encoder. Since it's a portable contained streaming appliance.
The last response I got from them was.
"Does this happen every time or only when you restart the profile shortly after stopping it? As a rule time codes are always an off set from 0. However, it does not matter what the time code is. It just matters that the server doesn't get an out of sequence time code. So if you stop an encoder and then start it too quickly you can send a time code to the server before the server has completely torn down the previous stream. You should wait several seconds before restarting a stream."
