/dev/dumbclocku; 9600 bps, 8-bits, no parity
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
localtime() routines will correctly convert back and forth between local and UTC.
Most of this code is originally from
refclock_wwvb.c with thanks. It has been so mangled that wwvb is not a recognizable ancestor.
Timecode format: hh:mm:ssCL
hh:mm:ss - local time
C - \r (carriage return)
L - \n (newline)
