Gantt chart view - choose timezone

[ColemanTom]

Problem

I was looking at the Gantt view to see timings and was getting confused because the time along the x-axis was local time. I was expecting UTC because that is what I was wanting - workflow is triggered/runs using UTC, so analysis of it I tend to do in UTC.

Proposed Solution

Provide the ability to choose timezone, or at least a switch to allow changing between Local and UTC. Or perhaps, have both visible along the x-axis.

Also, the x-axis should not just say Time, it should be Time (tz) where tz is the display timezone.
