20: <h4>Description</h4>
21: <p>This driver supports a dumb ASCII clock that only emits localtime at a reliable interval. 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>
22: <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>
23: <pre>
24: Timecode format: hh:mm:ssCL
25: hh:mm:ss - local time
26: C - \r (carriage return)
27: L - \n (newline)
