Programmers world-wide are interested in developing applications that can be used internationally. Part of the internationalization effort is the ability to engineer applications to use dates and times that conform to local calendars yet can inter-operate with dates and times in other calendars, for instance between the Gregorian and Islamic calendars. tZAMAN is a system that provides a natural language and calendarindependent framework for integrating multiple calendars. tZAMAN performs "runtime-binding" of calendars and language support. A running tZAMAN system dynamically loads calendars and language support tables from XML-formatted files. Loading a calendar integrates it with other, already loaded calendars, enabling users of tZAMAN to add, compare, and convert times between multiple calendars. tZAMAN also provides a flexible, calendar-independent framework for parsing temporal literals. Literals can be input and output in XML or plain text, using user-defined formats, and in different languages and character sets. Finally, tZAMAN is a client/server system, enabling shared access to calendar servers spread throughout the web. This paper describes the architecture of tZAMAN and experimentally quantifies the cost of using a calendar server to translate and manipulate dates.
