I've set the option on the below page to UTC

https://health.aws.amazon.com/health/status#settings

As I'm logged in, it persists across browser sessions.

It's worse.

Imagine you have two browser opening the same page, one showing UTC, another showing your local time.

There are no indicator showing which time zone is used. You have to mentally correlate "this browser windows has logged in..." with the time shown on screen.
