Google Search Engine, the mother of all the search engines can answer many simple queries. You can ask Google to tell you the local time anywhere in the world. To check the local time in London type the query What is time in London in Google Search box.
Did you notice the clock image on left side of the result? Hands of the clock point to the current shown in the result. So this image is dynamically generated when we submit the query to search engine.
