TSC-I2 is a software package to provide alternative to traditional gettimeofday() system call, and to provide more precise time at micro-second level. Its components include a user-mode daemon tsci2d, a C library libtsci2 and a set of utility tools as tsci2demo and tsci2measure. Current implementation supports IA32, AMD64 and Power PC architectures, as well as Linux, FreeBSD, Mac OS X and Microsoft Windows operating systems.
It's name consists of two parts: TSC is the 64 bit register that increments at CPU cycle speed, whose high resolution nature is taken advantage of; Internet2 is a consortium working on advanced next generation internet, who is a sponsor and user of this package. Possible Internet2 applications that will be using tsc-i2 include thrulay and owamp.
