History on web interface out of order

The history on the Web interface displays in the wrong order. Seems to be fine in my Android app. It happens many many times and is confusing at first. Here is what I see…

Zone 2 starts, Zone 4 starts, Zone 2 completes, Zone 4 completes

That makes it sound like Zone 4 started before Zone 2 ended. This goes on an on for whenever the two evens happen in the same minute, things can be out of order.
