NTP Download
Basic information on NTP can be found on our
NTP info page as well as in our
knowledge base articles.
The Meinberg NTP package provides a GUI setup program for Windows which installs the NTP service and associated executable programs that have been compiled from the original public NTP source code available at the
NTP download page at ntp.org.
The GUI installer also contains the corresponding HTML based NTP documentation, as well as the
libcrypto DLL from the
OpenSSL project,
which is required to create or check signatures of the NTP network packets, if the symmetric or public key authentication feature is used.
Unattended installation is also supported. Please see the
NTP Installer README
for help on how to use the installer.
Actually there a different stable NTP versions provided, plus some additional information:
- NTP package for current Windows versions (XP and later), with IPv6 support
- Outdated NTP package for Windows NT, Windows 2000, and newer, IPv4 only
- External Web Links
- NTP Cheat Sheet / Short Reference
- Linux driver for Meinberg plug-in radio clocks
For the Windows operating system there’s also an
NTP Time Server Monitor program
available which allows configuration of the local NTP service and graphical monitoring
of the local and remote NTP servers.
If you have any questions or feedback, please contact
ntp-support@meinberg.de.
NTP for current Windows versions (Windows XP and later), with IPv6 support
The current stable NTP version can be used with current 32 and 64 bit Windows versions (Windows XP and newer).
Beside the standard IPv4 network protocol it also supports IPv6.
Alternatively, there’s an older version available which can also be used on Windows 2000
or even Windows NT.
Note: The current setup program ntp-4.2.8p15a supersedes ntp-4.2.8p15 and ntp-4.2.8p15-v2.
It includes preliminary patches for some minor vulnerabilities, see
this KB page.
This package also includes the current openSSL libcrypto DLL v1.1.1t.
It is explicitly recommended to upgrade earlier installations to this version.

How to verify integrity of the downloaded file
Note:
If the NTP service fails to start after installation on Windows XP or Windows 7, the
Visual Studio Redistributable package my be missing,
althogh it should be available by default on all current Windows installations.
The 32 bit (x86) version of the redistributable is required even on 64 bit Windows systems.
The package is available from the Microsoft download page:
Go to Windows Download Center
Installation of the Redistributable Package (Screenshots)
NTP for Windows NT, Windows 2000, and newer, IPv4 only, without current security patches
This version of the NTP package is outdated but is still provided since it can also be used on Windows 2000 or even Windows NT.
It supports IPv4 only, but not IPv6. For current Windows installations the
current stable NTP version should be used which also contains current security patches.

Step 2: Select the components to be installed.
Step 3a (without initial configuration file):
for experienced users — the configuration file must be setup manually.
Step 3b: (initial configuration with external time server):
specification of up to 9 external NTP servers.
Step 3c (initial configuration with Meinberg Time Service):
Set up your own NTP server with built-in Meinberg reference clock (e.g. GPS180PEX).
Step 4:
Select the service settings (recommended «Use System Account»).

- David Taylor created a detailed step-by-step walkthrough of the installation
on his website. - The official documentation of the NTP Reference Implementation is included
in the setup program and will (optionally) be installed together with the binaries.
It is also available of the NTP documentation website.

NTP Cheat Sheet
NTP Cheat Sheet v1.0
(308 kB)
NTP Short Reference (A4, 2 pages), English language. Contains short lists of the most important NTP
configuration parameters, command line options and file formats used by NTP, e.g. for the keyfile
or the statistic files that can be generated by ntpd (loopstats, peerstats, clockstats, sysstats).
Linux driver for Meinberg plug-in radio clocks
A Linux driver for Meinberg PC plug-in cards is available on our
driver download page.
That driver is only required for plug-in radio clocks. Radio clocks
which are connected via a serial interface are directly supported by
NTP.

Довелось мне как то поработать с особо параноидально-жадным клиентом. Было закуплено куча китайских камер и несколько регистраторов на 64 канала. Камеры все были подключены по Onvif, потому часть с них могла синхронизировать время с регистратором, а часть не могла. Весь зоопарк неплохо показывал, но вот время на камерах прыгало спустя неделю-вторую. А все из-за того что на объекте не было интернета или локального NTP сервера, зато был охранник который 24 часа долбился в монитор на компе. На предложение поставить хотя бы простой роутер с сим-картой чтобы отрабатывал как ntp сервер ответ был один — это небезопасно и вообще за это наказывают (клиент с Дубая). В общем решением стало установка ntp сервера на компе охранника. И если время сбивается он просто переводит его на компе, и все камеры показывают нужное время
