Abstract
Accurate timing is an essential component for various areas of experimental research. Although expensive capture cards provide accurate time stamps for packets seen in networks, those do not help in synchronising applications or in-kernel processes. We present a moderate-cost approach to provide submicrosecond accuracy on common PC hardware using custombuilt clock card. The synchronisation accuracy is improved several orders of magnitude compared with synchronisation over network and an order of magnitude compared with pulseper- second signal on a serial port. Clock accuracy does not significantly suffer from a high I/O load on the computer.
