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> <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> <pre> Timecode format: Y yy/mm/ddCLZhh:mm:ssCL Y - year/month/date line indicator yy/mm/dd -- two-digit year/month/day C - \r (carriage return) L - \n (newline) Z - timestamp indicator hh:mm:ss - local time </pre> <!-- hhmts start -->Last modified: Sun Feb 14 11:57:27 EST 1999 <!-- hhmts end --> <hr> <script type="text/javascript" language="javascript" src="scripts/footer.txt"></script> </body> </html>
