In some cases, timestamps are inconsistent, causing the timeline to crash.

Describe the bug
In some cases, the timestamps for start are bigger than the ones for end, causing the timeline to crash.

To Reproduce
Uncertain of steps.

Expected behavior
The timeline should at least recover gracefully.

Can no longer reproduce, shelving until a build exhibiting this is found.

Cause identified: during a long build, durationMillis can be negative if a stage or step is queued/has to wait.

Tentative soln: add handling around negative durationMillis values.

Wonder if there is a way to detect build in progress? And show this too

Happened to my in progress build.

Stopped happening after it was done

Thanks for the report! Yeah, I think it might be because of how it handles idle waiting as negative time.

I also see this when one stage is waiting with waitUntil, it goes away once the build is finished.
