That's normal. For open source one is expected to use the source code as the reference. For closed source code, one is expected to supply the results to the support person without understanding them. Requiring detailed, end user, documentation for debugging output is generally seen as too much of an imposition on the coder, for open source, and as providing too much proprietary information, for proprietary code. > any.My ntp accepts pps and synchronises time every 16 secs.There are a lot of ntpd does not synchronise time every n seconds. It provides information to the kernel that micro-adjusts the time rather more frequently than this. It normally works in terms of adjusting frequency, rather than directly in terms of phase corrections. > key words used in the output ntpd -d and ntpd -D 3 and i would like to know > what each word means.Even google search did not yield great results.

For Linux or FreeBSD, these are generally within the kernel support for ntpd, rather than ntpd itself. The one possible processor dependency is that recent Intel architecture devices have a RDTSC instruction, to read a count of machine cycles, which might not exist for ARM, or might not be supported by the kernel software clock code for ARM. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
