The normal system clock can have sudden jumps if the system clock is
changed. Use the system monotonic clock to avoid these sudden changes
in time.
It appears the Raspbian OS (which is used by OctoPi) is setup to
update the system clock upon network connectivity. This could cause
sudden system clock changes which could lead to Klippy processing
errors. Using the monotonic clock eliminates these issues.

Instead of writing error messages to stderr, route them into the
python code and use the standard python logging system.
