clocktest \- Xenomai Clock Test
.SH "SYNOPSIS"
.sp
\fBclocktest\fR [\fIOPTIONS\fR]
.SH "DESCRIPTION"
.sp
\fBclocktest\fR 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\&.
.sp
For this program to work, you need to run a suitable Xenomai enabled kernel with the respective module (xeno_posix)\&.
