- 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.
