Overview
FSMLabs®TimeKeeper is a drop in replacement for NTP that is compatible with the NTP and PTP protocols. TimeKeeper Server connects directly to a time source, generates a high precision time for the local system and serves time to clients over the network using either the PTP or NTP protocols. TimeKeeper Client gets time over the network from either TimeKeeper Server or some other time source and generates a high precision local time for the local system. TimeKeeper Client may also act as a PTP master-clock or a NTP stratum server. uses either a standard server or PC timer or a high precision timer source such as the GPS pulse to synthesize a nanosecond timer and to synchronize that timer over networks with other machines. TimeKeeper permits a large-scale distributed trading system to operate on a single, global reference time value that enables improved latency intelligence, high precision time stamping, and reliable audit. Any number of other applications requiring tightly synchronized timers can benefit from the transparent operation our software solution that does not require specialized hardware. TimeKeeper reaches stable time fast, in seconds, and is highly tolerant of network delays and non-determinism. And TimeKeeper is 100% transparent to application code and the operating system: just start it up and automatically benefit from precision timing.

A technical summary
Real-Time Products
FSMLabs’ Enterprise RealTime Real-Time Management System (RTMS) for Linux. This successor to our old RTLinux product adds a optimized, modular, real-time subsystem to Linux using the dual-kernel virtualization technique we invented and patented (FSMLabs retains the exclusive license to this technology for enterprise applications.) A POSIX API and tight integration into Linux facilitate development of modular software components that have access to low microsecond real-time facilities, but can easily exchange data and control the operation of standard Linux applications. The interface is immediately accessible to programmers - requiring no Linux kernel programming - and allows creation of real-time threads in user space or (for the ultimate in speed) with direct access to hardware. All Linux drivers work normally and non-real-time performance is not compromised. Multi-processing is superbly supported.
The JSF-135 engine above was simulated and tested under the control of FSMLabs Software.
