REAL TIME CLOCK SYSTEM AND METHOD

摘要

A system and method for maintaining current time in an electronic device (130) utilizes time information received from an external time source (116). The time information is received via a communication interface and used to update or reset an internal time clock. The internal time clock keeps track of current time from that point forward using the updated or reset time. The internal time clock can make the current time available to one or more time-sensitive applications running within the electronic device, and the current time can be displayed to the user. Alarms can be set and stored in memory, and alerts generated when the alarm time is reached. The system and method can check for past due alarms and alert the user of the same upon the occurrence of a time update.
