Edit your crontab (~#> crontab -e) add a line on the 00's that
runs the ntpdate application<br>
00 * * * * /path/to/ntpdate pool.ntp.org<br>
:wq! to save it, and you will then be updated once an hour.<br>

servers that only have RTCMs
interfacing with radios. But when I use usb sound
interfaces (URI or usb
sound fob) then I find that ntpd causes anomalies in the
audio. Many
people don't notice it but I do and anyone with a good
ear will notice it and
comment about the audio sounding strange and blame it on
using a computer in
the audio path. <o:p></o:p></span></font></p>

use <b><span style="font-weight:bold">ntpdate</span></b>
once per hour and the

<br>
I have seen this in various systems and while it is
worse in slower single core
systems, it is still slightly present even in high end
quad core systems.<br>
But it is not present at all when using only RTCMs.<br>
