Abstract

A communication device. The device includes a memory storing original time difference data and a time difference database having a reserve of communication data and localized time difference data respectively corresponding to the communication data. The communication device is characterized in that when the communication device executes communication according to a communication code with the communication data, the communication device retrieves localized time difference information corresponding to the communication data from the time difference database and obtains the recipient'"'"'s local time data according to the original time difference data and the corresponding localized time difference data.

Claims

1. A communication device comprising a memory, wherein the memory stores:

original time difference data; and

a time difference database having a reserve of communication data and localized time difference data respectively corresponding thereto;

the communication device being characterized that;

when the communication device executes communication according to a communication code with the communication data, the communication device retrieves localized time difference information corresponding to the communication data from the time difference database and obtains a recipient'"'"'s local time data according to the original time difference data and the corresponding localized time difference data.

2. The communication device according to claim 1, wherein the communication code comprises telephone number data, and the communication data comprises country code and area code data.

3. The communication device according to claim 1, wherein the communication device is a cellular phone.

4. The communication device according to claim 1, wherein the communication device is a screen phone.

5. The communication device according to claim 1, wherein the communication device is a personal digital assistant (PDA).

6. The communication device according to claim 1, further comprising a data amendment module for amending the communication data and the localized time difference of the time difference database.

7. A method of obtaining recipient'"'"'s local time with a communication device, wherein the communication device comprises original time difference data and a time difference database having a reserve of communication data and localized time difference data respectively corresponding to the communication data, the method comprising the steps of:

executing communication according to a communication code with the communication data;

retrieving localized time difference information corresponding to the communication data from the time difference database; and

obtaining a recipient'"'"'s local time data according to the original time difference data and the corresponding localized time difference data.

8. The method according to claim 7, wherein the communication code comprises telephone number data, and the communication data comprises country code and area code data.

9. The method according to claim 7, wherein the communication device is a cellular phone.

10. The method according to claim 7, wherein the communication device is a screen phone.

11. The method according to claim 7, wherein the communication device is a personal digital assistant (PDA).
