Google slightly improved their onebox that shows the current time in different locations around the world, across the different time zones. For instance, you can enter time in moscow or time in berlin, germany or usa time. For one thing, the new time onebox result now shows different possible locations if the query is ambiguous (e.g. for the query usa time, locations range from Chicago to Washington or Denver). Also, the clock icon is now dynamic and shows the actual time... in gray/ silver when it’s night, and yellow/ gold when it’s day, apparently. The old time onebox was icon-less.
It seems time difference calculations can not be triggered though. Entering time difference germany china and similar will not show any onebox, even though it might be helpful.
