What is this for an offset?
This offset is a difference between the beginning of clock and the
actual start of the clock. The event will be recorded just after the
offset.
Sorry, I don't know what this means. What is the beginning of the clock
and what is the actual start?
From the CTF specification we have:
"The offset_s and offset fields indicate the offset from POSIX.1 Epoch,
1970-01-01 00:00:00 +0000 (UTC), to the zero of value of the clock. The
offset_s field is in seconds. The offset field is in (1/freq) units."

The CLOCK_MONOTONIC in RTEMS is based on the boot time. So, if you want
to give an offset value you have to figure out the CLOCK_REALTIME value
at boot time of the system. This is currently a secondary problem. I
would just omit the offset for now.
