Summary: Use monotonic clock for monitoring 
Category: None
Group: None
Resolution: None


Initial Comment:
The current logic uses time(2) to decide whether it is time to monitor again or not, however if the time is moved backwards monitoring will cease to be performed until the time difference is caught up. The attached patch switches the code to clock_gettime(2) using CLOCK_MONOTONIC.

Message:
The patch ignores the return value of clock_gettime(). Probably not a concern for Linux or FreeBSD, but Solaris documentation (for instance) does not list CLOCK_MONOTONIC:
