Hi! I am trying to figure out why NTP takes so long to react to oscillator changes... I want it to track the PPS from a Trimble Acutime as closely as possible.
When checking ntptime on startup I see that the NTP daemon is using PLL and starts the adjustment interval at 8 s. It then increases to 16, 32, 64, 128 and stops at 256. I read in the documentation that this limit should be 128 but is now 256. --- start from http://www.ntp.org/ntpfaq/NTP-s-config-adv.htm --- intervals 57 says that there were 57 calibration intervals. When PPS pulses are arriving, this number should increase. Each frequency adjustment requires a good calibration interval. The length of the current calibration interval can be found as interval 128 s (128 seconds is the default maximum length). Remaining numbers count abnormal conditions as explained below. --- end --- How can I make it stop earlier? At 64 s for example? Any ideas?
