Description

This driver supports the Chrono-log K-series WWVB receiver. 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.

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: 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
