Just under a week ago, I updated ntpsec to the latest
(ntpsec-1.1.3+) from ISTR 1.1.1. Since then, running a cronjob at
0000z with ntpviz, produces a nasty spike of local clock jitter,
offset and clock wobble. The system rapidly recovers.<br>

I now run the graph production nice'd to n -19 but there is no
discernible difference. No other cronjobs run at 0000z.<br>
<br>
I would be inclined to think my Raspberry Pi:<br>
Hardware revision 0010, Model B+<br>
Uputronics GPS board<br>
was inadequate but I don't recall such a performance hit with the
earlier 1.1.1<br>
<br>
I'm not sure what to try next; it seems inadequate to have to run
ntpviz away from the ntpsec R Pi. What have I missed ?<br>
