High Precision Time Service Software for Windows Platforms

ZTI Communications offers High Precision Time Service Software (TSS) for Windows platforms ensuring one millisecond guaranteed accuracy: TSS-N for use with a NTP server, TSS-P for use with a GNSS device via a communication port.

TSS-N :: Time Service Software for Windows NTP Clients

Today the Network Time Protocol (NTP) is widely used around the world, to synchronize the computers and provide a very precise time reference. NTP protocol supports an accuracy of time down to nanoseconds but the real accuracy which can be achieved depends on the operating system and the network performance.

NTP relies on a reference clock to define the most accurate time and synchronizes all clocks on a network to that of the reference clock. NTP uses Coordinated Universal Time (UTC) as the universal standard for current time. UTC is independent of time zones and enables NTP to be used anywhere in the world regardless of the time zone settings.

An NTP time server is used to obtain the correct time from a time source and adjust the local time in each participating computer. The time source used by the time server is very important as this forms the basis of time updates across the whole network. Recent studies show that the use of Internet time servers is not recommended for industrial or commercial applications: there are high numbers of bad clocks, unbalanced nature of the network load, security reasons…

So it is essential to use an accurate auditable time source such as a GNSS (Global Navigation Satellite System) source or an atomic clock.

An NTP time server synchronized by GPS for time synchronization on a computer’s network is an ideal professional level solution. But what is the uncertainty for the synchronized computer? (1, 10 or up to 50 milliseconds when using a NTP client on Windows computers).
And what is the time accuracy and uncertainty delivered to the applications running on the synchronized computer?

TSS-N software can be used with any Ethernet NTP time server. Based on a NTP client and sophisticated calculations and corrections algorithms, TSS-N delivers a very accurate time and indication of uncertainty, whose quality doesn’t drift during time and is independent of Windows system clock.

Key Benefits

• Ensures accurate time for applications running on Windows client machines
• Delivers precise time with uncertainty associated to the applications through an API
• Option to update or not Windows time
• TSS-N = Windows service running continuously and nothing else to do (no manual synchronization or parameters to adjust)
• Guaranteed accuracy of one millisecond for the PC running TSS-N thanks to the use of NTP and specific algorithms developed by ZTI Communications
• No more PC clock drift

Product requirements

• Windows Vista, Seven, 10, Server 2003, 2008 & 2012 / 32 or 64-bit platforms

License information

TSS-N software is licensed on a per workstation basis. You need to purchase a separate license for each PC you install it on.

TSS-P :: Time Service Software for Windows Clients with a GNSS device (COM or USB port)

High Precision Time Service Software TSS-P provides accurate time synchronization and updates automatically the PC clock. The software needs using a GNSS device via a communication port (USB / RS232 / RS422) providing 1PPS signal (Pulse Per Second) and NMEA messages (GGA, GSA, GSV, RMC, VTG).

Synchronized to GPS/UTC with the 1PPS signal delivered by the GNSS device, TSS-P delivers a guaranteed accuracy of one millisecond thanks to sophisticated calculations and corrections algorithms developed by ZTI Communications.

The PC clock is updated by TSS-P if the computer is not set to automatically synchronize with an Internet time server.

Key Benefits

• Ensures accurate time for applications running on the computer
• TSS-P = Windows service running continuously and nothing else to do (no manual synchronization or parameters to adjust)
• Guaranteed accuracy of one millisecond for the PC running TSS-P thanks to the use of specific algorithms developed by ZTI Communications
• No more PC clock drift
• Display: satellite information / geolocation information / UTC time and PC clock with the time zone / Last windows clock update / status (synchronized or not, synchronization in progress…)

Product requirements

• Windows Seven, 8 , 10, Server 2003, 2008 & 2012 / 32 or 64-bit platforms
