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 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 GPS 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?
ZTS: High Precision Zti Time Service Software on the end user computer provides accurate time synchronization and the related uncertainty to the applications. Note: ZTS can be used with any Ethernet NTP time server (provided by different manufacturers: Meinberg, Symmetricom and others...). We recommend the use of the model z300 with high precision and high reliability. Based on a NTP client and sophisticated calculations and corrections algorithms, ZTI time service delivers a very accurate time and indication of uncertainty, whose quality doesn’t drift during time and is independent of Windows/Linux or system clocks.
