From Dave in my basement
<p>Dave Taht is in my basement trying to use GPSD to set up NTP-independent time service on an WNDR3700 router, and having some problems.  I&#8217;m upstairs teaching GPSD to emit a clock-drift message &#8211;  both projects are because we&#8217;re trying to build a monitoring framework for accuracy-checking NTP. The following IRC exchange ensues:</p>
<pre>
[11:31]	dtaht2	looks like I have an underconfigured gpsd, miscompiled gpsd or ntp
[11:32]	dtaht2	OR does gpsd not provide time until it gets a full fix?
[11:32]	esr	That's correct.
[11:33]	dtaht2	yes, in terms of 'or' statements, the above evaluates to 'true'. However... which?
[11:33]	esr	Some devices report time from one satellite but you can't count on that. Most won't report time without 3 sats in view and good enough SNR.
[11:34]	dtaht2	cgps does report the time, so this particular device is
[11:35]	esr	OK, you have a problem somewhere else in the chain. And a learning experience just ahead of you.
[11:35]	dtaht2	and a dark tunnel ahead. There may be grues.
[11:36]	esr	Take your flashlight.
[11:36]	dtaht2	w;w;w;
[11:36]	esr	You see a rusty wand with a star on one end.
[11:37]	dtaht2	get wand; wave aimlessly
[11:38]	esr	Nothing happens.

<p>Actually, I went downstairs and said the last line to Dave rather than typing it.  He then laughed immoderately.</p>
<p>If you failed to understand the above, you are probably a normal human being and not an unregenerate geek who spends too much time in basements. This is sad for you.</p>
