This is a very old receiver without provisions for leap seconds, quality codes, etc. It assumes output in the local time zone, and that the C library mktime()/localtime() routines will correctly convert back and forth between local and UTC. There is a hack in the driver for permitting UTC, but it has not been tested.</p> 26 <p>Most of this code is originally from refclock_wwvb.c with thanks. It has been so mangled that wwvb is not a recognizable ancestor.</p> 27 <pre> 28Timecode format: Y yy/mm/ddCLZhh:mm:ssCL 29Y - year/month/date line indicator 30yy/mm/dd -- two-digit year/month/day 31C - \r (carriage return) 32L - \n (newline) 33Z - timestamp indicator 34hh:mm:ss - local time 35</pre> 36 <hr> 37 <script type="text/javascript" language="javascript" src="scripts/footer.txt"></script> 38 </body> 39 40</html> 41
