This program is designed to provide you with the local time in other cities and countries around the world as accurately as possible. We have built in the functionality to know when various locations around the world switch into and out of daylight savings. If you have struggled to find a program that does this well, you will also be pleased to note that we did not ignore the "difficult" locations that have extraordinary rules for their time rules. The map is fully clickable, so you can choose a city geographically, or via the list at the top of the screen. You can choose to see time displayed in 12 hour or 24 hour formats. You are also given some information along the bottom of the screen to relate the timezone you have selected to GMT / UTC and to your own local clock settings. Finally, there is also an option for a wakeup call, which is perfect for world travelers. You choose the location and tell us when, and our program will sound the alarm for you! Even if you don't leave home, it can be a useful feature to ensure you don't miss webcasts or events from around the globe.
