How to keep the GMT timezone in X axis

If you do that then the data for 'now' will either be off the front of the chart or there will be a gap between the edge of the data and the right hand side of the chart.

Another solution if you don't want the whole machine running in UTC is to run a virtual machine configured for UTC and run the browser in that.

Aha! How about this

In theory we could add an option to display the timestamp in UTC. Would need some thinking about to make sure it doesn't interfere with other options, but could be done.

I have pushed an update to dashboard master with an extra option to set X-axis to GMT.

you mean like this (in red circles) node red question

and for the link "change timezone of browser" that seems helpful
