When you absolutely have to know the time in London, Zurich, or Montreal it’s easily available at your fingertips with the Norfield Time Zone Clock. This clock easily tells you what time it is in 30 time zones, and the digital readout takes the guess work out of your time conversion. It also comes with two alarms so you can use it to wake you up, or alert you to events happening in a distant part of the world. This clock runs on three AAA batteries which are not included.
