Google Drops Current Time Search Operator?

In the past, a search in Google in the format of [time in location] would return a little clock at the top of the search results, with the current time in that location.

For example, a search on time in san francisco or current time in london would return the current time in those locations at the top of the Google search results.

It appears that this feature is currently not working anymore.

We know Ask.com added a real-time clock to their search results. So the same searches in Ask.com return the time in those locations. Try time in london or if you do a search just on london and scroll down and look on the right pane, you will see the real time clock.

Why did Google remove this feature from their search results? Was it a mistake, will it come back or is it gone forever?
