	Title		: Pulse-Per-Second API for UNIX-like Operating Systems, 
                          Version 1.0

RFC1589 describes a UNIX kernel implementation model for
high-precision time-keeping.  This model is meant for use
in conjunction with the Network Time Protocol (NTP,
RFC1305), or similar time synchronization protocols.  One
aspect of this model is an accurate interface to the
high-accuracy, one pulse-per-second (PPS) output typically
available from precise time sources (such as a GPS or GOES
receiver).  RFC1589 did not define an API for managing the
PPS facility, leaving implementors without a portable means
for using PPS sources.  This document specifies such an
API.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-mogul-pps-api-04.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
