Time in another Country / City button

Time in another Country / City button: this would be very useful! I imagine it would be quite easy to implement a button on the ZohoCRM contact that would return the time in another country / city - it would work the same as the "locate Map" button that opens up a google maps link. I think the Wolram Alfa service would work perfectly... for instance this link... http://www.wolframalpha.com/input/?i=time+in+sydney would detail the time in the contacts location with an auto reference to your own country.
