Description

[Roberto Agostino Vitillo (:rvitillo)]

In a sample dataset from Aurora I have noticed that nearly 1 every 1000 pings have a negative uptime value.

I see uptime (and TelemetryTimestamps etc.) using |new Date()| etc. - assuming broken or jumping client clocks, can the Date() implementation jump?

Avih mentioned that we actually have monotonic clock implementations, may we have to look into using them?

I have seen `let a = new Date(); f(); let b = new Date();` result in `b < a`, yes.

We're planning to remove "uptime" in favour of "totalTime". See bug 1485695.
