While time resolved astronomical observations are not new, the extension of such studies to sub-second time resolution
is and has resulted in the opening of a new observational frontier, High Time Resolution Astronomy (HTRA). HTRA
studies are well suited to objects like compact binary stars (CVs and X-ray binaries) and pulsars, while asteroseismology
of pulsating stars, occultations, transits and the study of transients, will all benefit from such HTRA studies.
HTRA has been a SALT science driver from the outset and the first-light instruments, namely the UV-VIS imager,
SALTICAM, and the multi-purpose Robert Stobie Spectrograph (RSS), both have high time resolution modes. These are
described, together with some observational examples. We also discuss the commissioning observations with the photon
counting Berkeley Visible Image Tube camera (BVIT) on SALT. Finally we describe the software tools, developed in
Python, to reduce SALT time resolved observations.
