Abstract

A method for dynamic time based entry adjustment based on daylight savings time changes in a mobile device comprising the steps of: translating at either the mobile device or a server a time based event having an event time and one or more event recipients into a universal time, the translating step removing any daylight savings time from the event time and performing a time zone adjustment; sending from the server to a device for each of the one or more event recipients the time based event with the universal time; and translating at the recipient device the time based event with universal time to a time based event with a local time; and adding the time based event with the local time to an application on the recipient device.

Claims

1. A method for dynamic time based entry adjustment based on daylight savings time changes in a mobile device comprising the steps of:

translating at either the mobile device or a server a time based event having an event time and one or more event recipients into a universal time, the translating step removing any daylight savings time from the event time and performing a time zone adjustment;

sending from the server to a device for each of said one or more event recipients the time based event with the universal time; and

translating at the recipient device the time based event with universal time to a time based event with a local time; and

adding the time based event with the local time to an application on the recipient device.

2. The method of claim 1, wherein the time based event is a calendar event and the application is a calendar application.

3. The method of claim 1, wherein the translating at the application step includes adding daylight savings time if the application is in a location with daylight savings time and the event time occurs during the daylight savings time at the location.

4. The method of claim 1, wherein the translating step, if at the server, checks whether the time based event is already in universal time, and if so, does not change the time on the time based event.

5. The method of claim 1, further comprising the steps of:

checking whether the mobile device has moved into a different time zone since the adding step and, if yes, performing said translating at the application and adding steps based on the different time zone.

6. The method of claim 5, wherein the time based event is stored at the mobile device in universal time.

7. The method of claim 1, wherein the translating at the server step removes daylight savings time from the event time only if the original time based event is scheduled to occur in daylight savings time in the location of the event originator.

8. A mobile device with for dynamic time based entry adjustment based on daylight savings time changes characterized by means for:

receiving from the server a time based event with a universal time;

converting the time based event with universal time to a time based event with a local time, said conversion including performing a time zone adjustment to a local time zone and adding daylight savings time if the time based event occurs in daylight savings time at the location of the mobile device; and

adding the time based event with the local time to an application on the recipient device.

9. The mobile device of claim 8, further including means for:

creating a new time based event having an event time and one or more event recipients;

translating the new time based event into a universal time, the translating step removing any daylight savings time from the event time and performing a time zone adjustment; and

sending to the server the time based event with the universal time.

10. The mobile device of claim 8, wherein the time based event is a calendar event and the application is a calendar application.

11. The mobile device of claim 8, further comprising means for:

checking whether the mobile device has moved into a different time zone since the adding step

12. The mobile device of claim 11, wherein the time based event is stored at the mobile device in universal time.

13. The mobile device of claim 8, wherein the means for translating removes daylight savings time from the event time only if the original time based event is scheduled to occur in daylight savings time in the location of the event originator.
