CLOCK_MONOTONIC issue

[Giuliano Colla <giuliano.colla@fastwebnet.it>]

Hi all,

in order both to profile the performance of my rt threads, and to 
perform timed operations (such as sem_timedwait), I'm using the 
clock_gettime() function.

Using as a parameter CLOCK_REALTIME everything appears to work as 
expected, but if I attempt to use CLOCK_MONOTONIC (which should be a 
more reliable timing source, from what I read), I get bogus times.

This occurs on different platforms, and with different kernel 
versions/rt patch. (3.10.10-rt7 - 3.10.67-rt71 - 3.12.31-rt45).

Am I missing something obvious, such as a kernel misconfiguration, or 
this is something to be expected?

Any hint will be appreciated.

Thanks in advance,

Giuliano
