`
`
`
`
`
`
`
`
`
`
`A time zone management system and method for a date-
`
`
`y
`&
`
`
`
`
`
`
`
`book like application. A user can associate a time zone with
`
`
`
`
`
`an event or appointment, especially on a palmtop computer.
`
`
`
`
`
`
`
`
`The event can be associated with the time zone byselecting
`
`
`
`
`
`
`
`the time zone as an attribute from a details menu, or other
`suitable user interface mechanism or other mechanism. The
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`user can select a display time zone, and all events to be
`
`
`
`
`
`
`
`
`displayed are translated to the display time zone to be
`
`
`
`
`displayed on the palmtop computer.

`
`
`
`FIELD OF THE INVENTION
`
`
`
`
`
`
`
`
`
`
`
`
`
`This invention relates generally to the field of computer
`
`
`
`
`
`
`programs implementing date-book like applications. More
`
`
`
`
`
`
`
`
`particularly, this invention relates to a time zone manage-
`
`
`
`
`
`
`
`
`ment method and apparatus particularly suitable for a palm-
`
`
`top computer.
`
`BACKGROUND OF THE INVENTION
`
`
`
`
`
`
`
`20
`
`
`
`
`
`
`
`As the components required to build a computer system
`
`
`
`
`
`
`
`have reduced in size, new categories of computer systems
`
`
`
`
`
`
`
`
`have emerged. One of the new categories of computer
`
`
`
`
`
`
`systems is the “palmtop” computer system. A palmtop
`
`
`
`
`
`
`computer system is a computer that is small enough to be
`
`
`
`
`
`
`
`
`held in the hand of a user and can be “palm-sized.” Most
`
`
`
`
`
`
`
`palmtop computer systems are used to implement various
`
`
`
`
`
`
`Personal Information Management (PIM)applications such
`
`
`
`
`
`
`
`
`as an address book, a daily organizer(i.e., a date-book like
`
`
`
`
`
`
`application) and electronic notepads, to name a few.
`
`
`
`
`
`
`
`Among the most popular features of such palmtop com-
`
`
`
`
`
`
`
`
`puters is the daily organizer which operates on the palmtop
`25
`
`
`
`
`
`
`computer and synchronizes to a similar application on a
`
`
`
`
`
`
`
`user’s desktop computer. Such applications of the palmtop
`
`
`
`
`
`
`
`computer have made managing appointments and events
`
`
`
`
`
`
`
`
`
`easier and more convenient for many users. However, rapid
`
`
`
`
`
`
`
`advances in communication and travel have caused many
`
`
`
`
`
`
`
`
`people to commonly have dealings with associates all over
`
`
`
`
`
`
`
`the world. This makes management of an event calendar
`
`
`
`
`
`
`
`
`more challenging due to the need to operate across multiple
`
`
`
`
`
`
`
`time zones. Heretofore, the date-book functions of computer
`
`
`
`
`
`
`
`applications in general including palmtop computers has
`
`
`
`
`
`
`
`
`been inadequate to deal with the problems associated with
`
`
`
`
`
`
`maintaining a calendar of events occurring in multiple time
`zones.
`
`

`

`
`
`
`
`
`
`
`
`
`
`
`
`2
`
`
`
`
`
`
`
`
`can be associated with the time zone by selecting the time
`
`
`
`
`
`
`zone as an attribute from a details menu, or other suitable
`user interface mechanism or other mechanism. The user can
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`select a display time zone, andall events to be displayed are
`
`
`
`
`
`
`
`translated to the display time zone to be displayed on the
`
`
`
`
`
`
`palmtop computer. This provides many advantages includ-
`
`
`
`
`
`
`
`
`ing simplifying the use of the palmtop computeracross time
`
`
`
`
`
`
`zones so that events can be entered directly in a particular
`
`
`
`
`
`
`
`
`remote time zone, but displayed in another time zone of the
`
`
`user’s choosing.
`
`
`
`
`
`
`
`
`In one embodimentconsistent with the present invention,
`
`
`
`
`
`
`a method of management of time zone information in a
`
`
`
`

`DETAILED DESCRIPTION OF THE
`
`
`INVENTION
`
`
`
`
`
`
`
`
`
`
`
`In the following detailed description of the present inven-
`
`
`
`
`
`
`
`
`
`tion, numerous specific details are set forth in order to
`
`
`
`
`
`
`provide a thorough understanding of the present invention.
`
`
`
`
`
`
`
`
`However, it will be recognized by one skilled in theart that
`
`
`
`
`
`
`
`
`the present invention maybepracticed withoutthese specific
`
`
`
`
`
`
`
`details or with equivalents thereof. In other instances, well
`
`
`
`
`
`
`
`known methods, procedures, components, and circuits have
`
`
`
`
`
`
`
`not been described in detail as not to unnecessarily obscure
`
`
`
`
`aspects of the present invention.
`Notation and Nomenclature
`
`
`
`
`
`
`
`
`
`
`Someportions of the detailed descriptions which follow
`
`
`
`
`
`
`
`are presented in terms of procedures, steps, logic blocks,
`
`
`
`
`
`
`processing, and other symbolic representations of operations
`
`
`
`
`
`
`
`
`on data bits that can be performed on computer memory.
`
`
`
`
`
`
`
`
`These descriptions and representations are the means used
`
`
`
`
`
`
`
`
`
`
`
`by those skilled in the data processing arts to most effec-
`
`
`
`
`
`
`
`
`tively convey the substance of their work to others skilled in
`
`
`
`
`
`
`
`
`the art. A procedure, computer executed step, logic block,
`
`
`
`
`
`
`
`
`process, etc.,
`is here, and generally, conceived to be a
`
`
`
`
`
`self-consistent sequence of steps or instructions leading to a
`
`
`
`
`
`
`
`
`desired result. The steps are those requiring physical
`
`
`
`manipulations of physical quantities.
`
`
`
`
`
`
`
`
`Usually, though not necessarily, these quantities take the
`
`
`
`
`
`
`
`
`
`form of electrical or magnetic signals capable of being
`
`
`
`
`
`
`stored,
`transferred, combined, compared, and otherwise
`
`
`
`
`
`
`manipulated in a computer system.It has proven convenient
`
`
`
`
`
`
`
`
`at times, principally for reasons of common usage, to refer
`
`
`
`
`
`
`
`
`to these signals as bits, values, elements, symbols, charac-
`
`
`
`
`
`ters, terms, numbers, or the like.
`
`
`
`
`
`
`
`
`
`
`It should be born in mind, however, that all of these and
`
`
`
`
`
`
`
`
`
`similar terms are to be associated with the appropriate

`
`
`
`
`
`
`
`computer system, or similar electronic computing device,
`
`
`
`
`
`
`
`that manipulates and transforms data represented as physical

`
`
`
`
`Time Zone Management in Accordance with the Invention
`
`
`
`
`
`
`While this invention is susceptible of embodiment
`in
`
`
`
`
`
`
`
`
`many different forms, there is shown in the drawings and
`
`
`
`
`
`
`
`will herein be describedin detail specific embodiments, with
`
`
`
`
`
`
`
`
`
`the understanding that the present disclosure is to be con-
`
`
`
`
`
`
`sidered as an exampleof the principles of the invention and
`
`
`
`
`
`
`
`
`not intended to limit the invention to the specific embodi-
`
`
`
`
`
`
`
`
`
`ments shown and described. In the description below, like
`
`
`
`
`
`
`
`
`reference numerals are used to describe the same, similar or
`
`
`
`
`
`
`
`corresponding parts in the several views of the drawings.
`
`
`
`
`
`
`Turning now to FIG. 1, an exemplary date-book display
`
`
`
`
`
`
`
`20 showing a daily view (contrasted to a weekly or monthly
`
`
`
`
`
`
`
`
`view) for a selected date such as that which appears in
`
`
`
`
`
`
`
`
`version 3.0 the Palm Operating System by Palm Computing,
`
`
`
`
`
`
`
`
`
`
`Inc, Santa Clara, Calif. The date is shown in block 24 and the
`
`
`
`
`
`
`
`
`
`day of the week is shown in block 28. The time blocks in the
`
`
`
`
`
`
`
`
`
`
`day are illustrated as a grid having an array of entries
`
`
`
`
`
`
`
`adjacent time blocks in a manner similar to that used in
`
`
`
`
`
`
`
`conventional paper date books. In one embodiment, such as
`
`
`
`
`
`
`
`
`implemented in version 3.0 of the Palm Operating
`that
`
`
`
`
`
`
`
`
`
`System from Palm Computing, Inc., the user enters dates
`
`
`
`
`
`
`
`directly into the date-book application by selecting a time
`
`
`
`
`
`
`
`
`
`
`(by tapping the spaceto the right of the time using a stylus
`
`
`
`
`
`
`
`
`ona touch sensitive touch-screen that serves as a display and
`
`
`
`
`
`
`
`
`
`input device) and entering a notation adjacent the time using
`
`
`
`
`
`
`
`
`a form of writing designed for handwriting recognition
`
`
`
`
`
`
`
`
`called the “Graffiti®” alphabet (Graffiti is a registered trade-
`
`
`
`
`
`
`
`
`mark of Palm Computing, Inc.). Text then appears adjacent
`the selected time. The time can be refined and other
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`attributes added by selection of “details” button 34 (by
`
`
`
`
`
`
`
`
`
`
`tapping the button with the stylus). Thus,
`to enter an
`
`
`
`
`
`
`
`
`
`appointment or event starting at 6:00 pm, the user taps the
`
`
`
`
`
`
`
`
`
`space 38 adjacent the 6:00 pm indication and then enters the
`
`
`
`
`
`
`
`
`
`event in a special area of the device designated for data
`
`entry.
`
`
`
`
`
`
`
`FIGS. 2-7 generally illustrate an exemplary user interface
`
`
`
`
`
`
`
`
`with various user interface elements including menus, win-
`
`
`
`
`
`
`
`
`
`
`dows, icons, buttons, data entry boxes, etc. that provide the
`
`
`
`
`
`
`
`
`
`
`user with the ability to enter data and make selections
`
`
`
`
`
`
`
`consistent with embodiments of the present invention. Those
`
`
`
`
`
`
`
`
`
`
`skilled in the art will appreciate that there are many waysto
`
`
`
`
`
`
`
`
`
`provide userinterfaces and the exact user interface described
`
`
`
`
`
`
`
`herein should not be considered limiting to the scope of the
`
`
`
`
`
`
`
`
`invention, but should be considered as
`an_
`illustrative
`
`example.
`FIG. 2 illustrates an extension of the above event man-
`

`
`
`
`
`
`
`
`
`
`various time zones. In this illustration, display 100 incor-
`
`
`
`
`
`
`
`porates features similar to that of display 20 and in general,
`
`
`
`

`desired time andthen enters the eventin a special area of the
`
`
`
`
`
`
`
`
`
`device designated for data entry. In the example shown, an
`event 112 identified as “CONFERENCE CALL WITH
`
`
`
`
`
`
`
`YOSHIDA”has been entered and stored in association with
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`a time block starting at 6:00 pm and ending at 7:00 pm. This
`
`
`
`
`
`
`
`
`
`event is still selected as indicated by the shading of the
`“6:00” time indicator 116. In order to alter the time zone or
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`make other entries associated with the date and time, the
`
`
`
`
`
`
`
`
`
`
`user can select the “details” button 120 (by tapping the
`
`
`
`
`
`
`button with a stylus) to bring up an “EVENT DETAILS”
`20
`menu 130. This menu can be used in a conventional manner
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`to add notes, alarms or other attributes to the event. In
`
`
`
`
`
`
`
`accordance with one embodiment of the present invention,
`
`
`
`
`
`
`
`
`
`
`
`this menu can also be used to change the time zone asso-
`
`
`
`
`
`
`
`
`
`
`
`ciated with the event (the event time zone). The user can
`
`
`
`
`
`
`
`select a default time zone as a device preference to prevent
`the need to enter an event time zone unless it deviates from
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`the default time zone. This default time zone appears in
`block 136 and will be associated with an event unless
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`specifically changed by the user.
`30
`
`
`
`
`
`
`
`
`
`In order to change the time zone associated with the
`
`
`
`
`
`
`
`
`
`currently selected event, the user selects the “TIME ZONE”
`
`
`
`
`
`
`
`
`block 136 in the EVENT DETAILS menu(again, by tapping
`
`
`
`
`
`
`
`
`the block with a stylus) to bring up a list of time zones in a
`
`
`
`
`
`
`
`“SELECT TIME ZONE” menu 210 asillustrated in display
`35
`200 of FIG. 3. The user can then select a time zone to be
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`associated with the event. In this illustrative example, the
`
`
`
`
`
`
`
`Tokyo time zone is selected as indicated by shading of box
`
`
`
`
`
`
`
`
`220. In one embodiment, selection of that event time zone
`
`
`
`
`
`
`
`
`
`will then cause the selected time zone to be temporarily
`
`
`
`
`
`
`
`
`
`reflected in the time zone display 104, but this is not to be
`
`
`
`
`
`
`
`limiting, since the display time zone is managed in a
`
`
`
`
`
`
`
`
`separate manner as will becomeapparentlater. The list of
`
`
`
`
`
`
`
`
`time zones in menu 210 may be a default list containingall
`
`
`
`
`
`
`
`possible world time zones in one embodiment. In another
`
`
`
`
`
`
`
`
`
`embodiment, the menu may contain only the most recently
`
`
`
`
`
`
`
`
`
`used time zones. In yet another embodiment, the user can
`
`
`
`
`
`
`
`select an array of time zonesto be displayed during a setup
`
`
`
`
`
`
`
`
`procedure. Other variations are also possible within the
`
`
`
`
`scope of the present invention.
`Once a time zone has been associated with the event as
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`described aboveor using any suitable alternative for making
`
`
`
`
`
`
`such an association,it is saved as an attribute associated with
`
`
`
`
`
`
`
`
`
`the event. The user can display appointments and other
`
`
`
`
`
`
`
`
`
`events in any display time zone and the appointment(event)
`times are translated from the stored event time zone to the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`display time zone. This is illustrated in display 400 of FIG.
`
`
`
`
`
`
`
`
`
`
`4, wherein the display time zone is the default time zone,
`
`
`
`
`
`
`
`whichin this illustrative example is Central European Time
`
`
`
`
`
`
`
`
`as shown in area 104. Displayed in Central European Time,
`60
`
`
`
`
`
`
`
`
`the event 112 is shifted in time by eight hours to 10:00 am
`
`
`
`
`
`
`
`
`
`
`as shown 410 so that the event can be readily understood and
`coordinated with other events in the local time.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`If the user wishes to change to another display time zone,
`
`
`
`
`
`
`
`
`
`
`the user can select the time zone button 420 to bring up a
`“CURRENT TIME ZONE” menu 515. The user can then
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`adjust the display time zone as desired. In this example, the
`
`
`
`
`
`
`
`
`
`current time zone(the display time zone) can be changed to
`
`40
`
`
`6
`
`
`
`
`
`
`
`
`
`Tokyo time by selecting the TOKYO block 525 from menu
`
`
`
`
`
`
`
`
`
`515. This causes the display 500 to indicate Tokyo time at
`
`
`
`
`
`
`
`
`
`104 and shift the event 112 to 6:00 pm asillustrated in
`
`
`
`
`
`
`
`
`
`display 600 of FIG. 6. Those skilled in theart will appreciate
`
`
`
`
`
`
`
`
`that other events might also be scheduled in a particular day
`
`
`
`
`
`
`
`
`
`and those events would similarly shift with selection of a
`
`
`
`
`
`
`
`
`
`new time zone. In generally, the user can select a default
`
`
`
`
`
`
`
`
`time zone to prevent the need to enter either a display or an
`event time zone unless it deviates from the default time
`
`
`
`
`
`
`
`
`
`zone.
`
`
`
`
`
`
`
`
`Time zones are commonly associated with a numberof
`
`
`
`
`
`
`
`
`hours difference (plus or minus) from Greenwich Mean
`
`
`
`
`
`
`
`
`Time (GMT). Thus, in order to translate between two time
`
`
`
`
`
`
`
`
`
`
`zones, the difference between the two time zones and GMT
`
`
`
`
`
`
`
`
`can simply be subtracted. For example, Tokyo time is
`GMT+9 hours while Eastern U.S. Standard Time is GMT-5
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`hours. Thus, to translate a time between these two time
`
`
`
`
`
`
`
`
`zones, one simply subtracts so the difference is 14 hours. In
`
`
`
`
`
`
`
`
`
`many cases, the date might also require correction in any
`time zonetranslation and should be reflected in block 24.
