First off, great work on these barnowl projects. We've been using them for years with great success. Second, I would open a discussion for this question since it's not really an issue, but it looks like that feature hasn't trickled down to this repo yet.
I am simply curious if there's a way to get more accurate message receipt timestamps. Right now I believe each message from barnowl gives the timestamp in milliseconds.
Questions:
How accurate is the timestamp of receipt?
Are there any technical limitations that prevent recording a more precise timestamp?
If the platform is Raspberry Pi, is it possible to couple an ultra-precise RTC module and leverage that hardware when calculating the timestamp?
