Bug Description

In testing a unity8 branch that wanted to make use of QInputEvent timestamps, I discovered that they seem a bit unreliable in Mir (testing on a mako).

I often would get 0. And the timestamps themselves would be all over the place, seemingly overflowing. See https://pastebin.canonical.com/142915/ for a log (the MIKE lines indicate true/false for whether the event is an autorepeat event and then the next number is the Qt timestamp).

Might be an issue with stuffing int64 into a ulong? Or might be something else random. I'm trying to get a tighter test case.
