Abstract
A system for indicating to a message subscriber when a message has been left for that subscriber accommodates multiple time zones by providing information to the subscriber related to the subscriber's time zone indicating that the message was left. When the caller leaves his message, the caller's time zone is determined based the caller's phone number's time zone determined from a database corresponding these data. Then the subscriber's local time zone is determined. The difference in time zones is determined and the time indicated to the subscriber is related to the subscriber's time zone, not the caller's, by adding or subtracting the appropriate amount of time indicated by the difference in time between the time zones to give the subscriber the time of the call in the subscriber's local zone.
