Abstract

There is disclosed a method, system and program product for automatically adjusting location based system information in a mobile computer to reflect the time zone where a user of the mobile computer connects to the Internet, as a function of the geographic location of the IP address of the connection, as seen by an address server remote from the connection place. A table mapping the IP address of the computer with each other IP address where the mobile computer connects to the Internet and corresponding time zone data is constructed with minimal user interaction each time a new Internet connection is made. Thereafter, anytime the user connects to the Internet at an IP address in the table, location based system information is appropriately adjusted with no intervention by the user.

Claims

1. A method for automatically adjusting location based system information in a mobile computer upon use thereof at a location different than its place of usual Internet connection, comprising:

upon connection to a network including the Internet, polling a server to find an IP address as seen by the Internet for said computer;

searching for an entry in a table, in said computer, containing said IP address from the Internet;

if no entry is found, adding a table entry containing a mapping of said IP address from the Internet with an actual IP address of said computer;

prompting a user to supply a time zone, correlated to a present geographic location, for inclusion in said table entry; and

adjusting location based system information in said computer using said time zone correlated to said IP address from the Internet and said computer IP address.

2. The method of claim 1 wherein said adding step additionally comprises:

determining whether a table exists; and

if not, building a table.

3. The method of claim 1 wherein said adding step additionally comprises:

prompting a user of said computer to supply a location designation indicative of a geographic location corresponding to said connection.

4. The method of claim 1 wherein said polling step comprises:

contacting said server; and

in response to said contacting step, reporting said IP address to said computer.

5. The method of claim 1 wherein said adjusting step includes:

changing, as needed, status messages in configuration files of said computer; and

setting time in a clock in said computer.

13. The computer program of claim 11 wherein said means for adding additionally comprises:

interactive means for prompting a user of said computer to supply a location designation indicative of a geographic location corresponding to said connection.

6. Apparatus for automatically adjusting location based system information in a mobile computer upon use thereof at a location different than its place of usual Internet connection, comprising:

means active upon connection to a network including the Internet for polling a server to find an IP address as seen by the Internet for said computer;

means for searching for an entry in a table, in said computer, containing said IP address from the Internet;

means active if no entry is found for adding a table entry containing a mapping of said IP address from the Internet with an actual IP address of said computer;

means for prompting a user to supply a time zone, correlated to a present geographic location, for inclusion in said table entry; and

means for adjusting location based system information in said computer using said time zone correlated to said IP address from the Internet and said computer IP address.

7. The apparatus of claim 6 wherein said means for adding additionally comprises:

means for determining whether a table exists; and

means active if no table exists for building a table.

8. The apparatus of claim 6 wherein said means for adding additionally comprises:

interactive means for prompting a user of said computer to supply a location designation indicative of a geographic location corresponding to said connection.

9. The apparatus of claim 6 wherein said polling means comprises:

means for contacting said server; and

means active in response to said means for contacting for reporting said IP address to said computer.

10. The apparatus of claim 6 wherein said means for adjusting includes:

means for changing, as needed, status messages in configuration files of said computer; and

means for setting an appropriate time in a clock in said computer clock.

11. A computer program having data structures included on a computer readable medium for automatically adjusting location based system information in a mobile computer upon use thereof at a location different than its place of usual Internet connection, comprising:

means active upon connection to a network including the Internet for polling a server to find an IP address as seen by the Internet for said computer;

means for searching for an entry in a table, in said computer, containing said IP address from the Internet;

means active if no entry is found for adding a table entry containing a mapping of said IP address from the Internet with an actual IP address of said computer;

means for prompting a user to supply a time zone, correlated to a present geographic location, for inclusion in said table entry; and

means for adjusting location based system information in said computer using said time zone correlated to said IP address from the Internet and said computer IP address.

12. The computer program of claim 11 wherein said means for adding additionally comprises:

means for determining whether a table exists; and

means active if no table exists for building a table.

14. The computer program of claim 11 wherein said polling means comprises:

means for contacting said server; and

means active in response to said means for contacting for reporting said IP address to said computer.

15. The computer program of claim 11 wherein said means for adjusting includes:

means for changing, as needed, status messages in configuration files of said computer; and

means for setting an appropriate time in said computer.
