This has no 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.</p> 25 <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> 26 <pre> 27Timecode format: hh:mm:ssCL 28hh:mm:ss - local time 29C - \r (carriage return) 30L - \n (newline) 31</pre> 32 <hr> 33 <script type="text/javascript" language="javascript" src="scripts/footer.txt"></script> 34 </body> 35 36</html> 37
