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> 26182007Sroberto <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> 27182007Sroberto <pre> 28132451SrobertoTimecode format: Y yy/mm/ddCLZhh:mm:ssCL 29132451SrobertoY - year/month/date line indicator 30132451Srobertoyy/mm/dd -- two-digit year/month/day 31132451SrobertoC - \r (carriage return) 32132451SrobertoL - \n (newline) 33132451SrobertoZ - timestamp indicator 34132451Srobertohh:mm:ss - local time 35132451Sroberto</pre> 36182007Sroberto <hr> 37182007Sroberto <script type="text/javascript" language="javascript" src="scripts/footer.txt"></script> 38182007Sroberto </body> 39132451Sroberto 40290001Sglebius</html> 41
