It is similar in purpose to <em>ntpdate</em>, but of course obtains time not from ntp but from the GPS receiver.</p> <p>This is particularly useful for RTC-less systems without network connectivity, which come up with a completely wrong system clock that needs to be properly set as soon as th GPS receiver finally has acquired a signal.</p> <p>I <a class="reference external" href="http://lists.ntp.org/pipermail/hackers/2013-June/005926.html">asked the ntp hackers if they were interested</a> in merging it into the official code base, and their response was (summarized) that with a then-future release of ntpd this would no longer be needed. So the <em>gpsdate</em> program remains an external utility.</p> <p>So in case anyone else might find the tool interesting: The source code can be obtained from <a class="reference external" href="http://git.sysmocom.de/gpsdate/">http://git.sysmocom.de/gpsdate/</a></p>gpslinuxhttps://laforge.gnumonks.org/blog/20151101-gpsdate/Sat, 31 Oct 2015 16:00:00 GMT
