I'm sometimes confused by UTC and how it relates to the daylight savings time of my timezone. Could we get a little timestamp at the bottom of every page in UTC?
Why would we want to break caching for anonymous users every second of every day? :(
Beyond that, the UTC time is on your /recent page. Click the envelope at the top of the page and see.
edit: see the dropdown on your user name; it contains the current UTC time.
