<h4>Description</h4>
|
||
|
|
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.
|
||
|
|
|
||
|
|
<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.
