[chrony-users] Improving local clock error

["STR ." <strykar@xxxxxxxxxxx>]

Hi,

I see a constant ~15 ppm error in my local clock graphs using an
Uputronics uBlox MAX-M8Q GPS.

How do I improve this, set 'maxclockerror' to 10 or 13 ppm?

root@apu:~# chronyd -v
chronyd (chrony) version 3.4 (+CMDMON +NTP +REFCLOCK +RTC +PRIVDROP
-SCFILTER -SIGND +ASYNCDNS -SECHASH +IPV6 -DEBUG)

root@apu:~# uname -a
Linux apu 4.14.82 #0 SMP Tue Dec 4 11:28:56 2018 x86_64 GNU/Linux

chrony.conf - https://paste.ubuntu.com/p/8xvM7zzjGN/
chronyc log - https://paste.ubuntu.com/p/4SYks6ZR4S/

What else could I do to improve clock performance?

Cheers,
