I was hoping the code was already written. My ultimate goal is to get my clocks within 1ms.I've recently managed to get nearly all systems consistenly within 5-20ms. In the introduction of "Generic Nanosecond Kernel Timekeeping", they state that "...the primary purpose of these modifications is to improve timekeeping accuracy to the order less than a millisecond and, ultimately, to a nanosecond ...". In downloading the code I wasn't entire sure what it included. Regardless, after running the test scripts, it appeared that my kernel and hardware could in fact get to within a millisecond. My next question was, how do I get that improvement into my environment. The answer from my vendor was 2 part: 1. get a PPS kit for my Spectracom time server and 2. get the appropriate PPS implementation for my client systems. In looking around the internet, I've found a few postings that led me to believe that people have this working for other linux implementations that were NTPv4 and various kernel revs. Is this making sense? Thanks for your time. Allen _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
