ATOMCLK - Atomic Clock Synchronization

Introduction
============

This Windows Sockets  Application  allows you to  synchronize your
CPU time-of-day (TOD)  clock  with any daytime server available on
the internet. Many Naval observatories maintain atomic clock times
and will allow you to connect to  their  daytime server using this
application. A correction can  be  made to allow you to compensate
for the timezone difference  of  remote  daytime  servers. You can
configure  this  application to query the daytime server  once, or
periodically.  This  is  useful  for  keeping  a  (public  access)
slip/terminal server from disconnecting  your session in the event
of   a   long   period  of  non-activity.  A  correction  for  the
transmission  delay  is also incorporated in an attempt to provide
you  with  the  most  accurate  time  as  possible.  The  clock is
synchronized within at least  500ms. This application makes use of
the UDP protocol to query a TCP/IP  daytime  server on port 13 and
was  written  as  an  introduction to Windows Sockets programming.
