1. NAME
clocktest - Xenomai Clock Test
2. SYNOPSIS
clocktest [OPTIONS]
3. DESCRIPTION
clocktest is part of the Xenomai test suite and tests the Clock. For each CPU, it repeatedly prints a time offset (compared to the reference gettimeofday()), a drift value, the number of warps and the maximum warp in microseconds.
For this program to work, you need to run a suitable Xenomai enabled kernel with the respective module (xeno_posix).
