What's New in version 5.2?

Precision Time Protocol

• Domain Time II now supports IEEE 1588-2008/2019 Precision Time Protocol (PTP).

• When using PTP, Domain Time II can adjust the system timing upon the receipt of each synchronization packet. This option is enabled by default, and provides a continuously variable (up to 64 times per second) adjustment of the computer’s time, yielding a much smoother and more precise alignment than is available with traditional request-response time protocols. Results in the laboratory environment have achieved sub-microsecond or a few microseconds in accuracy over periods of time exceeding four hours.

Audit Server and Manager

• Audit Server now supports a new “Standby Mode,” or hot-spare paradigm. You can set up a secondary Audit Server and have it ready to take over instantly if the primary server goes offline.

• Multiple Real-Time Alert targets can be set for both client and server. You may choose to have both targets notified, or use the second as a fail-over if the first does not acknowledge the alert.

• Manager now remembers your selections after performing a batch operation and re-highlights the selected machines.

• Manager now can backup and restore the audit list database, either from the menu or from the command line.

• See the complete list of upgrades, changes, and recommendations on the Changelog page.

What's New in version 5.1?

Overall Improvements:

• Full support for Windows Server 2008 R2 and Windows 7.
  
• New look and easier to use control panels and interfaces
  
• Native IPv6 capability
  
• Support for multicast
• More logging levels and details, easier-to-use log viewer on components.
  
• Better email alerting and configuration, support for SMTP authentication, html/text MIME types, etc.
• Components that use reference clocks can use multiple time sources and time samples for improved accuracy.

Improvements in Server and Client:

• More accurate and efficient - sub-millisecond accuracy in many cases
  
• New API and SDK to provide access to hectonanosecond precision timestamps
  
• Special algorithims to compensate for internal timing changes on newer OS's (Vista, 2008, 2008 R2, Win7)
  
• Single unified Windows Client (no more need for Thin or Ultra-Thin Clients)
• Can now specify unlimited number of time sources
  
• Can specify number of time samples to request of time sources for greatly improved accuracy
  
• Various auto-discovery wizards for assistance in finding and configuring reliable time sources
  
• Can use Active Directory policy to configure sources and accuracy settings
  
• Now with full Windows timestamp authentication, can totally replace Windows Time, even on Domain Controllers
  
• Includes NTP authentication, compatible with all NTP clients and servers
  
• Improved support for multi-core processor systems
  
• Improved performance on virtual machines
  
• Easy access to many advanced clock control settings and clock training on the CPL
• Remote Connection to other Domain Time systems from any Server or Client machine
  
• Easier configuration: Import/export all settings to an editable .reg template file
  
• Full settings backup/restore
  
• Start/Stop Domain Time Service from within Domain Time CPL
  
• Syslog capability
  
• SNMP traps and alerts
  

Improvements in Manager

• Unified display of all machines and systems.
  
• Fully integrated installation and control of Monitor, Update Server, and Audit Server.
  
• Much faster and robust discovery of network machines
  
• Can supply various credentials to connect to multiple domains
  
• Uses Active Directory to discover machines
  
• Able to use multicast for discovery on remote subnets
  
• Uses new standard registry files (.reg) as template files for installation/upgrade/reset configurations of remote machines
  
• Can install/upgrade and manage both 32-bit and 64-bit machines from one copy of Manager
  

Improvements in Audit Server

• Audit Server integrates directly into Manager, using the same machine lists and discovery processes. You can select any machine for audit directly from Manager.
  
• Faster, more robust auditing
  
• More intelligent and flexible email reporting/logging/alerting.
  
• SNMP traps and alerts
• Real-time alerts of poor synchronization (instead of only at Audit Time)

Improvements in Monitor and Update Server

• Monitor uses multicast for more reliable discovery of remote machines
• Monitor has improved email alerting and formatting
• Update Server integrates completely with Manager, using the same machine discovery lists
• Update Server can use installation template files for custom install/upgrades
