> Storage should be in UTC, data can be converted for display

Sometimes we need to speak about events (verbally), or share screenshots of graphs, dashboards, or other data. We can make a habit of always stating the time zone when we talk, and make sure every dashboard/graph contains a time offset.

Or we can just pick a single arbitrary time zone and always use that.

There are a few internal tools at Google that assume your local time zone (I'm in EDT) -- those are far more confusing.

Has this really been a problem? A date+time is unambiguous. I can only see this being confusing if California follows through with abolishing DST.

...so pick UTC then?

Why is that any different than how it is right now for anyone not in the Pacific timezone?
