Abstract
A communication device such as pager (100) includes a real-time clock circuit (118). The real-time clock circuit keeps track of both the pager's home time zone information (402) and the pager's current time zone information (404). While the pager user is operating within his home area, the pager's home time zone information (402) and the current or local time zone information (404) will be the same. If the user however travels away from his home system's time zone, the real-time clock circuit adjusts the current time zone information (404) to reflect the time zone the user is currently operating in. The user can set alarms which reference either the home time zone information (402) or the current time zone information (404). This allows for more user flexibility on how the alarm conditions are to operate.
