The server 206.108.0.131 part of 0.pool.ntp.org is returning the wrong date and time. Not sure if this is the best place to post this.
If you look at this graph here it seems like it should have been kicket out of the pool automatically:
My servers older nortel phone switch hung onto it and rolled all my clocks back.
I am sorry to hear that. To me it sounds like a poor NTP implementation by Nortel. Most NTP implementations do some kind of sanity checks when it recieves a bad time all of a sudden.
If it is not possible to do any changes to the Nortel phone switch you might want to consider to have it sync time against an internal ntp server that syncs against e.g. 4 different NTP servers. The internal NTP server can then provide the sanity check the Nortel seems to lack.
This is PublicTimeServer001077 < Servers < Network Time Foundation's NTP Support Wiki , part of ntp.org stratum one server list. They recently changed IPv6 address. For me the refid is .PTP0. , I do not know what kind of device it is.
We tried that, the Nortel switch hated our internal ntp servers as they are appliances and the clock floated a bit, very fussy, except they had no problem turning themselves back almost 11 hours against this server… will have to figure out a better way to do the ntp.
What about using NIST or UNSO time servers?
It’s precision time protocol… Usually those master clocks are high dollar appliances (which use GPS as their time source). I wonder if it was a firmware glitch?
Thanks for the info.
TORIX support said the problem was due to a software update.

Hi @rjesse,
Sorry about that! The monitoring system noticed within 15 minutes (which is the current monitoring interval). What time did your client get this IP? The timestamp from your screenshot is unclear.
If you have a google account you should be able to see the monitoring data
I couldn’t figure out to save/export the data from the web UI there, so a paste from ClickHouse below. Only IPs with a score > 10 are included in the DNS system.
SELECT
ts,
score,
offset,
leap,
error
FROM ntppool.log_scores
WHERE (dt > '2019-07-02') AND (dt < '2019-07-05') AND (server_id = 26543) AND (monitor_id = 0) AND (ts > '2019-07-03 03:27:00') AND (ts < '2019-07-03 20:07:00')
ORDER BY ts ASC
