Hello!! I have time jumps made by ntpd because gpsd sometimes puts wrong data to SHM because of wrong data from gps receiver(very bad chips)
I have only one time source in ntp.conf — 127.127.28.1 with PPS enabled I want to add another two internet sources for stability but at first i want to emulate wrong data from gpsd to see how ntpd will make this time jump. As first step i read data from SHM when gpsd worked correctly at 14 p.m. today UTC+3 for 30 minutes And after that i stopped gpsd and launched my own binary at 17:30 p.m. UTC+3 writing that old data to SHM. I expected the great offset and the time jump after some time(as it was when receiver lied) but what i saw was: - without binary launched ntpd had no updates — it’s correct (no data — no action) - with binary launched ntpd had a little offset for all 30 minutes without any attempt to correct system time please give me some help!! Maybe i don’t understand ntpd — gpsd communication correctly or smth else Thank you in advance _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
