This shouldn’t be a feature request, it’s a bug. If you’ve got a timezone setting in the user profile that is honored across APM but totally ignored in Insights, it’s an inconsistency in the app and should be fixed.
It’s further aggravating when importing a graph from APM into an insights Dashboard, where the dates in that graph will be in the selected timezone but the rest of the Dashboard is still in whatever timezone the browser happens to be in.
And no, changing the browser’s timezone isn’t a fix. It’s needed for other things where it’s actually useful, and should be ignored here.
Please fix this guys, it’s been 2 years.
