A time zone identifier for a geographic location is generated by receiving a request, including a first information portion in the time zone identifier that represents a time difference between a standard time and a local base time for the geographic location, and, if there exists a rule specifying when the geographic location observes daylight saving time, including a second information portion identifying the rule in the time zone identifier. Otherwise, the second information portion is not included. A computer-readable data structure for a time zone identifier includes a first attribute for the first information portion and a second attribute for the second information portion. A computer system includes a rule repository and a time zone management module.
