That would be a different issue, though.  If interrupts are lost or clock tick interrupt rates are not accurate, the system time will be wrong.  But that would not cause the "monotonic" clock to go backwards.  A supposed monotonic value going backwards is just a bug, no matter what the clock source is doing.
