I find that ticket disturbing reading.

The original description seems to claim there is a logic bug in 
LoopingCall that is triggered when the clock goes back, but subsequent 
discussion is all about the pros and cons of monotonic clocks.

Is there such a bug, and if so should there be a separate ticket for it?

Independent of monotonic clocks, it seems clear that LoopingCall 
stopping and never restarting is bad. Being called with the wrong 
interval is tedious, but far less serious, surely?
