WinSNTP
-------

WinSNTP is an implementation of the Simple Network Time Protocol and
runs as a Windows application.  SNTP is a subset of the Network Time
Protocol described in RFC-1305.  NTP is a set of algorithms
and protocol that is designed to keep a distributed set of computer
clocks synchronized to the correct time with a very high degree of
accuracy.

WinSNTP uses SNTP to synchronize the clock of a PC running Windows
to within 100-200 mS of the time information provided
by an NTP server.  The time is corrected for differences in time zones
and daylight savings time.  WinSNTP will periodically poll the NTP
server in order to keep the PC clock accurate within a configurable
limit.  The poll interval is extended or reduced to maintain the
accuracy of the PC clock and balance this with the load placed on the
NTP server.

WinSNTP uses the Winsock TCP/IP Sockets interface to access the network
services required to implement SNTP.  WinSNTP has been tested with a
large number of Winsock compliant TCP/IP products and verified for
correct operation.  See the WinSNTP Help information for a list of
the TCP/IP stacks known to interoperate at the time of release.

To use WinSNTP you need a PC running Microsoft Windows equipped with
network access and a Winsock compliant TCP/IP implementation.  WinSNTP
will operate correctly over a wide range of different network connections
from SLIP links to high speed local area networks.

You will also need access to an NTP server - contact you local system
or network administrator for pointers to a nearby NTP server.

WinSNTP has extensive help and configuration information that provides
an on-line reference and users guide.


Note on BWCC.DLL
----------------

BWCC.DLL is a dynamic link library containing the Borland Custom Window
Controls.  This DLL is commonly used to give applications a more modern
look and feel than the original Windows style of controls and windows.

While BWCC.DLL is BACKWARD compatible with earlier versions, WinSNTP requires
a compatible release of BWCC.DLL.  WinSNTP will check the version of BWCC.DLL
that is loaded when WinSNTP is run and will output a fatal error message if
the version of BWCC is incompatible.

When WinSNTP is run, it asks Windows to load the BWCC.DLL; Windows will look
in:
	a) Memory to see if the DLL is already loaded.
	b) The working directory
	c) The WINDOWS\SYSTEM directory
	d) All directories on the search path (DOS PATH)
to try and locate the DLL.

Note that if you run another application that has an incompatible version
of BWCC in its directory, the incompatible version will be loaded into memory
and WinSNTP will issue its error message and abort.

The version of BWCC.DLL supplied with WinSNTP is the latest version as of
August 1994.  Its file size is 157,472 bytes.

If WinSNTP displays its fatal error that the version of BWCC found is
back level, you need to find the incompatible versions of BWCC on your
system AND DELETE THEM.  You should exit Windows BEFORE beginning your
search since Windows locks a DLL when it is loaded.  You will not be able
to delete a loaded DLL while Windows is running.

The best approach is to keep a single copy of BWCC.DLL in your WINDOWS\SYSTEM
directory and share this version across all the applications that use the
Borland Custom Controls.  Not only will this save you disk space but it
enables you to easily upgrade and manage your PC in the future.


Installation
------------

Installation of WinSNTP is very straight forward.

1. Create a directory on your hard drive;

	mkdir \winsntp

IMPORTANT!
*********
2. Make sure that this directory is included in your DOS PATH
   or alternatively, after you have unpacked the .ZIP file, copy
   the file BWCC.DLL to a directory currently listed in the PATH
   or to your WINDOWS\SYSTEM directory.

   WinSNTP requires BWCC.DLL to be available either in WINDOWS\SYSTEM
   or in a directory in your PATH.  An error message will be displayed
   if WinSNTP cannot load the file.

3. Change to the newly created directory;

	cd \winsntp

4. Unpack the .ZIP archive using PKUNZIP into the current directory;

	pkunzip a:wsntp15f.zip

5. Run the Windows Program Manager.  Using the File|New option, create
   a new program item called WinSNTP. Fill in the dialog box as follows;

	Description:		WinSNTP
	Command Line:		x:\winsntp\winsntp.exe
	Working Directory:	x:\winsntp

	Where x: is the drive containing the \winsntp directory.

6. Copy the file BWCC.DLL to your WINDOWS\SYSTEM directory and then
   delete the copy in the \winsntp directory.  See the section Note on BWCC
   above.


Thats it!  You can run WinSNTP by double clicking on the WinSNTP icon.
