SYSTEM REQUIREMENTS
SNTP Service runs on the following operating systems:
Windows™ 7 • Vista Server 2008 • Server 2003 • XP
SNTP Service runs in native 32-bit or 64-bit mode on x86 processors from AMD, Intel and other vendors.
Please see the Frequently Asked Questions
for security considerations of remote administration under Windows 7, Vista and Server 2008.
SNTP Service Software
Advanced synchronization software for
Simple Network Time Protocol
- For any size network or one PC
- Highly optimized, low-overhead design uses minimal resources
- Constant monitoring and adjustment of system clock (no time warps or jumps)
- Compensates for network delays
- Includes easy, powerful control panel applet and tiny, fast service application
- Control panel can be used remotely to configure, monitor, troubleshoot and track
- Client/Server approach supports deployment in enterprise networks
SNTPService is time synchronization client/server software for the more advanced user.
It maintains network time synchronization services
under 32-bit and 64-bit versions of Windows™ 7, Vista, Server 2008, Server 2003 and XP.
While an effective tool for the desktop, it also includes important features for enterprise network deployment.
From a single workstation, an administrator can remotely configure, monitor, troubleshoot and track
licensing of enterprise-wide SNTPServ client and server components.
SNTP Service software consists of two components:
-
The first component is an application that runs in the background as a Windows service,
performing various time synchronization tasks. This application is constantly running,
so it must be small and fast. Therefore, it does not have a graphical user interface (GUI),
and does not include Microsoft Foundation Classes (MFC). This drastically reduces memory requirements,
lowers system overhead and consumes less of the host's resources.
-
The second component is the control panel applet. It is run from the system control panel
to set up synchronization parameters. It provides the required control interface to the small service application (above),
and monitors, tracks and troubleshoots service components.
A key advantage is the use of 'clock slewing' when synchronizing incorrect system time.
Let's say your system clock says 8:23, but it is really 8:20. Most clock synchronizers will 'step' the clock back,
instantly setting it to the correct time. This can cause serious problems with many software applications (often databases)
that can't handle backwards time travel.
SNTP Service avoids this problem by slowing down the incorrect clock until it lines up with real time (i.e. clock slewing).
This method avoids any issues with software sensitive to time warps.

SNTP Service Software Technical Notes:
-
The built-in control panel applet transparently uses WMI to allow the management and monitoring of the SNTPService
running on local or remote systems.
-
Customers with advanced requirements can create VB scripts that interface directly with WMI in order to create their own additional custom,
enterprise-wide time management schemes.
-
The service application (that runs in the background) has been specifically optimized to execute as a
Windows™ 7, Vista, Server 2008, Server 2003 and XP service with access to a Winsock 2 network API.
-
Full SNTP client and server functions are incorporated, in complete compliance with RFC2030 - Simple Network Time Protocol (SNTP) version 4.
