WorldTimer is a user configurable world clock that can display a number of clocks using different time zones. Each clock can be configured to display with either a digital or analog clock face. The user is able to configure the appearance of the clocks to suit their own tastes. Almost all aspects are user configurable, including the font and colour used to display text. Clocks may be digital or analog and a combination of both may be displayed at the same time. In addition to this, it contains the ability to add user configurable countdown timers.
