組件
The Domain Time II version 5.2 system consists of these components (older versions that run on other platforms can be found here):
Domain Time II Server
High-accuracy multi-protocol time server for Windows able to serve time to virtually any device. Can act as part of the Domain Time distribution hierarchy or independently. Completely replaces the Windows Time (w32time) Service.
Domain Time II Client for Windows
High-accuracy time client for Windows: Remotely configure using Manager. Completely replaces the Windows Time (w32time) Service.
Domain Time II Client for Linux (DTLinux)
High-accuracy time client for Linux: Configurable via .conf files or remotely using Manager.
Domain Time II Management Tools
Install, configure, analyze, test, and monitor your entire Domain Time system from your desktop.
Manager
The master control center for your Domain Time system. Can remotely install, upgrade, monitor, and track licenses of Domain Time on any machine across your network - from a single desktop!
Monitor Service
Automatically monitors the synchronization of critical systems and provides real-time alerting of errors, also provides advanced variance reporting and historical records.
Update Server
Automatically watches the network to keep your machines updated with current versions of the time software. Can automatically install time software on new machines as they come online without administrator intervention.
Other Tools
A full suite of testing, diagnostic, and utility programs to augment the simple, trouble-free use of Domain Time II on your network.
Domain Time II Audit Server
Collects time sync data from Domain Time components and stores them to create a secure audit trail.
Software Development Kit (SDK)
Provide your applications programmatic access to Domain Time's internal high-precision (hectonanosecond) timestamps.
Manageability Features
Benefit - Saves you money! Installation and ongoing maintenance/troubleshooting are the single largest costs in today's IT environment. Domain Time offers you the ability to reduce or even eliminate the significant costs involved in configuring time on your various systems. Your valuable IT personnel can spend their time on other issues.
» Components can be installed, upgraded, and configured network-wide from a single workstation using the Management Tools.
» Clients automatically discover the correct time servers and protocols.
» Components automatically configure their Windows Firewall to allow the necessary time protocols.
» Monitor time status network-wide and raise out-of-sync alarms using Monitor Service or Audit Server.
» Complete compatibility with Windows Active Directory, including graphical utility to monitor and configure the Windows Time service.
» Advanced time analysis tools, including real-time graphical displays of accuracy and latency.
» Windows time zone settings can be set remotely using the Management Tools.
» Comprehensive documentation and excellent technical support.
Accuracy Features
Benefit - Everything Works! Since your systems always have the correct time, all of your time-dependent systems run properly. Users can always log in, your expensive clustering servers and storage systems keep humming, your email and accounting systems always have the correct date and time, etc. Accurate time helps your IT investment pay off.
» Server and Clients run as system services, machines sync automatically whether or not someone is logged in.
» Clients accessing via dial-up or VPN sync automatically when a connection to the network is activated.
» Uses sophisticated network latency and clock drift data algorithms to provide millisecond accuracies, even over WAN links
» Time source averaging among multiple sources to determine the likely best "true time".
» Configurable clock slewing to synchronize time without time jumps or setting the clock backwards.
» Clock training to adjust local clock rate to be more accurate.
» Your choice of high-efficiency trigger/cascade hierarchy or high-accuracy broadcast time distribution methods
» Innovative precision clock management and tuning controls to easily achieve maximum accuracy on any system
Redundancy Features
Benefit - No hassles! Systems do occasionally fail. Servers crash; network infrastructures can break down. Domain Time II just deals with it, without requiring user intervention. So, when everything else isn't working, the last thing you have to worry about is the time.
» Components compare among various sources and automatically choose the most reliable source.
» Multiple levels of fallback in case of network error or server unavailability.
» Time hierarchy collapses gracefully to compensate for failed/unreachable components:
· Slave Servers can automatically assume the Master Server role in the event of a failure.
· Clients automatically fallback to any available Slave, then to the Master, then to any available server.
» Components can try alternate time protocols if primary protocol fails.
» Audit Server can be set to replicate and auto-fallback to secondary Servers (such as in Disaster Recovery locations).
Security Features
Benefit - Peace-of-mind! As most IT managers are aware (sometimes from painful experience), disruption of vital systems can come from the most unexpected of sources. The best systems take these possibilities into account, from the basic design on up. Domain Time II helps you ensure the time portion of your infrastructure is hardened against intruders and blunderers, which results in more uptime for your business.
» Domain Time II uses your existing domain (Active Directory tree/forest) structure and access permissions.
» Works with or without Active Directory enabled.
» Administrative permissions required to change configuration settings.
» Clock change monitor prevents manual tampering with the system time and date.
» Logged-in users do not need clock-changing permission.
» Supports serving and obtaining the time through existing firewalls.
» Built-in Denial of Service and IP access lists for unparalleled protection from malicious and inadvertent interference with network time.
Verifiability Features
Benefit - You're accountable! You need to know and to be able to demonstrate that your electronic records are correct. In fact, many industries are already operating under regulations that require an audit trail of time synchronization. Domain Time II allows you to automatically provide compliance with these requirements, without requiring any additional work for employees, or having to implement expensive custom systems.
» Components keep detailed log files with selectable retention options and real-time log viewer.
» Graphical displays and raw time drift data is available on time sync components.
» System tray icon provides instant visual feedback of correct system sync.
» Alerts are generated and logged if time is not being synced correctly.
» Complete time sync data can be automatically collected centrally into a secure audit trail.
Domain Time II 系統需求
Older versions are provided for backwards-compatibility only. Fixes, updates, and technical support are available only for the supported version.
* If you need this older version, please write to Greyware Tech Support.
Domain Time II Version 5.2 新版基本系統需求
These are the system requirements for the current version of Domain Time II (except where noted). System requirements for older versions are here.
- Windows XP, 2003 (&R2), Vista, 2008 (&R2), Win7, Win8.x, 2012 (&R2), Win10, Win11, 2016, 2019, 2022, 2025
- 32-bit (x86) and 64-bit (x64) versions available. ARM is not supported.
- Linux x86_64 distro running in 64-bit mode. Kernel version 2.6.30 (minimum), version 3.0 or later (preferred),
- with systemd init service controller (not the older inet.d "SysV" type)
- 64-bit (x64) Intel-architecture. ARM is not supported.
- Hardware: Typically, any Intel-architecture machine capable of running Windows (32 or 64-bit) or Linux (64-bit) may run Domain Time.
- Machines running Server require sufficient memory for packet buffering and maintaining the number of TCP/UDP connections used (varies by the number of client machines contacted). Machines running Manager/Audit Server also require sufficient disk space for holding collected audit records (see the Application Notes below).
