World clock Why a world clock? When traveling abroad, as well as planning a trip, a world clock is one thing you certainly need! When you have some experience with planning (business) trips, you will realize the importance of time management. This is not only important at planning domestic travel, but certainly at planning international trips. Time zone map A time zone map will give you a global idea of the world time zones in all parts on the planet. This is practical when you are planning a international trip, with more than one destination. Together with information like flight duration and departure and arrival time you can plan an extra night in a hotel, when necessary. By the way, it's always wise to build in some extra (rest)time between time of arrival and the first appointment. This will give the traveller to get acclimatized and refresh. International time clock Use this world clock when you need to know the exact time in a specific place on earth. This is not only practical when planning a trip, but it is also very convenient when you need to make an international phone call, and you don't want to disturb the person you call in his sleep!
