<h4>Description</h4>
|
||
|
|
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>Most of this code is originally from refclock_wwvb.c with thanks. It
|
||
|
|
has been so mangled that wwvb is not a recognizable ancestor.
