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> 22132451Sroberto <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> 23132451Sroberto <pre> 24132451SrobertoTimecode format: hh:mm:ssCL 25132451Srobertohh:mm:ss - local time 26132451SrobertoC - \r (carriage return) 27132451SrobertoL - \n (newline) 28132451Sroberto</pre> 29132451Sroberto <hr> 30132451Sroberto <!-- hhmts start -->Last modified: Sun Feb 14 12:07:01 EST 1999 <!-- hhmts end --> 31132451Sroberto <hr> 32132451Sroberto <script type="text/javascript" language="javascript" src="../scripts/footer.txt"></script> 33132451Sroberto </body> 34132451Sroberto 35132451Sroberto</html>
