An electronically generated simultaneous display of the local time within multiple time zones in the world is adjusted to accommodate local time arising from Daylight Saving Time. A preferred modified south polar projection of the Earth which schematically depicts the Northern Hemisphere is divided into geographical time zones. Each geographic time zone is associated with a time marker that points to an adjacent time scale. Either the geographical time zones or the time markers are adjusted in order to correctly display the ongoing time changes resulting from the continuous observation of Daylight Saving Time in time zones of the world. As further features, a user may adjust the display to present a hypothetical time and the corresponding times experienced in different time zones around the world. A user may have a specific time zone highlighted by invoking data, such as a city name, a telephone area code or an address book contact reference, which is associated with specific time zone. Conversely, highlighting a time zone may invoke a list of data associated with that time zone, e.g. city names, countries.
