I was already wondering a bit why that check never triggered for anyone. It is easy to have a non-monotonic clock (there's lots of crappy hw and the gettimeofday code has to work hard) and the effects of time warps are subtle, if noticeable at all, so i expected some detections. i have released -rt13 with another change: the other timer warning is only printed once.
