Hi Thomas,

I switched my custom kernel timer to use the ktimers with the prio of -1
as you mentioned to me offline. I set up the timer to be monotonic and
have a requirement that the returned time is always greater or equal to
the last time returned from do_get_ktime_mono.

Now here's the results that I got between two calls of do_get_ktime_mono

358.069795728 secs then later 355.981483177. Should this ever happen?

Are you running NTP ?
