What are the steps to reproduce?

With a non-UTC local timezone, create a chart and specify As UTC for the X-axis label. Feed the chart with regular data and let a graph build up. Then refresh the browser.

What happens?

After the browser refresh the timestamp shown at the right hand end of the chart is shown in local time. Historical timestamps are correctly in UTC.

What do you expect to happen?

All timestamps should be in UTC

More information, it doesn't appear to be entirely consistent, sometimes it works. I haven't worked out the failing conditions yet.

OK, got it, it works ok until the screen is refreshed. I will updated the description.
