`TIME ZONE MANAGEMENT
`
`FIELD OP 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
`
`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 namea few.
`Among the most popular features of such palmtop com-
`puters is the daily organizer which operates on the palmtop
`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.
`
`Consider for example the following situations:
`
`1. You are in France and schedule an appointment for a
`phone call with someone in California. You both want to
`deal with the same time and time zone to create the appoint-
`ment, butstill see at whattime this will translate in your own
`local time zone.
`
`2. You are in France and schedule an appointment for a
`phonecall with someone in California while youwill be in
`Tokyo (or maybe you don’t even know where you will be at
`the appointment time). You want to use the California time
`to set the appointment, and see it displayed in your local
`time, even if you have changed time zonesince yousetit.
`
`3. You are in France, and schedule a meeting with someone
`in California, but this meeting will take place in Tokyo. You
`both want to be able to use Tokyo time.
`
`SUMMARY OF THE INVENTION
`
`The present invention relates generally to methods and
`apparatus for time zone management, particularly with
`palmtop computers. Objects, advantages and features of the
`invention will become apparent to those skilled in the art
`upon consideration of the following detailed description of
`the invention.
`
`In one embodimentofthe present invention, a time zone
`management system and method for a date-book like appli-
`cation lets a user associate a time zone with an event or
`appointment, especially on a palmtop computer. The event
`
`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 mechanismor 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. 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
`calendar application, includes storing an event associated
`with a block of time: storing a time zoneattribute associated
`with the event: establishing a display time zone for display
`of events; translating the block of time associated with the
`event fromthe stored time zone to the display time zone; and
`displaying the event as occurring at the translated block of
`time.
`
`A palmtop computer having time zone information man-
`agement, consistent with certain embodimentsof the present
`invention has a programmed processor and a display. A
`calendar application runs on the programmed processor to
`store an event associated with a block oftime, the calendar
`application further operating to: store an event time zone
`attribute associated with the event; store a display time zone
`for display of events; translate the block of time associated
`with the event fromthe stored time zone to the display time
`zone; and meansfor displaying the event as occurring at the
`translated block of time on the display.
`A palmtop computer having time zone information man-
`agement, consistent with an embodiment ofthe present
`invention has a programmed processor, a display and a user
`interface. A calendar application runs on the programmed
`processorto store an event associated with a block of time,
`the calendar application further operating to: store an event
`time zoneattribute associated with the event; store a display
`time zone for display of events: translate the block of time
`associated with the event from the stored time zone to the
`display time zone: displaying the event as occurring at the
`translated block of time in a daily time grid on the display;
`wherein the display time zone is established by a user
`selection from a display time zone user interface element
`forming part of the user interface: wherein the event time
`zone is established bya user selection from an event time
`zone userinterface element forming part of the user inter-
`face.
`
`The above summaries are intended to illustrate exemplary
`embodiments of the invention, which will be best under-
`stood in conjunction with the detailed description to follow,
`and are not intended to limit the scope of the appended
`claims.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`In the following detailed descriptionof 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 the art 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 ofoperations
`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 oftheir 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 stepsor 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 commonusage, to refer
`to these signals as bits, values, elements. symbols, charac-
`ters, terms, numbers, or thelike.
`It should be born in mind, however,that all of these and
`similar terms are to be associated with the appropriate

`physical quantities and are merely convenient labels applied
`to these quantities. Unless specifically stated otherwise as
`apparent from the following discussions, it is appreciated
`that throughout the present invention, discussions utilizing
`terms suchas “processing” or “computing”or “translating”
`or “selecting”or “translating” or “displaying” or “recogniz-
`ing” or the like, refer to the action and processes of a
`computer system, or similar electronic computing device,
`that manipulates and transforms data represented as physical
`(electronic) quantities within the computer system’s regis-
`ters and memories into other data similarly represented as
`physical quantities within the computer system memories or
`registers or other such information storage, transmission or
`display devices.
`
`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 described in detail specific embodiments, with
`the understanding that the present disclosure is to be con-
`sidered as an exampleofthe 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 ofthe 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 shownin block 24 and the
`day of the week is shownin block 28. The time blocksin 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
`that
`implemented in version 3.0 of the Palm Operating
`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 adjacentthe time using
`a form of writing designed for handwriting recognition
`called the “Graffiti®” alphabet (Grafliti 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
`appointmentor event starting at 6:00 pm, the user taps the
`space 38 adjacent the 6:00 pmindication and then enters the
`event in a special area of the device designated for data
`entry.
`FIGS. 2~7 generallyillustrate an exemplaryuserinterface
`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 ways to
`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-
`agement mechanism to account
`for events occurring in
`various time zones. In this illustration, display 100 incor-
`porates features similar to that of display 20 and in general,
`the palmtop computer implementing the present invention
`can carry out any or all of the function of the currently
`available palmtop computers, such as the Palm VII™ palm-

`515. This causes the display 500 to indicate Tokyo timeat
`104 and shift the event 112 to 6:00 pmasillustrated in
`display 600 of FIG. 6. Those skilled inthe art will appreciate
`that other events might also be scheduled in a particular day
`and those events would similarly shift with selection ofa
`newtime zone. In generally, the user can select a default

`currently displayed time zone. Ofcourse, those skilled in the
`art will appreciate that the current display time zone (the
`time zone associated with the current date-book application
`display—referred to herein as the display time zone) can be
`indicated in other manners than that shown.
`In one exemplary embodiment,
`in order to enter an
`appointment or event, the user taps the space adjacent the
`desired time and thenenters the event in a special area of the
`device designated for data entry. In the example shown, an

`Elements of the various user interfaces not explicitly
`discussed herein operate in a manner similar to that of
`conventional elements as used in the Palm Operating System
`version 3.0.
`
`With the invention described, the exemplary situations
`discussed previously are readily handled as follows:
`
`1. You are in France and schedule an appointment for a
`phone call with someone in California. You both want to
`deal with the same time and time zoneto create the appoint-
`ment, but still see at what time this will translate in your own
`local
`time zone. In this case you simply decide on the
`commontime zone and both parties use this time zone for
`the event and display time zones.
`
`2. You are in France and schedule an appointment for a
`phonecall with someone in California while you will be in
`Tokyo. You want
`to use the California time to set
`the
`appointment, and see it displayed in your local time, even if
`you have changed timezonesince yousetit. In this case you
`simply set the appointment using California time as the
`event time and set the display time for the current time zone
`you are in.
`
`3. Youare in France, and schedule a meeting with someone
`in California, but this meeting will take place in Tokyo. You
`both want to be able to use Tokyo time. In this case, both
`parties can simply use Tokyo time for the event time. The
`time canbe displayed using the display time as Tokyo time.
`Many other scenarios present
`themselves and can be
`handled in a similar manner.
`
`Those skilled in the art will recognize that the present
`invention has been described in terms of exemplary embodi-
`ments based uponuseofa programmed processor. However,
`the invention should not be so limited, since the present
`invention could be implemented using hardware component
`equivalents such as special purpose hardware and/or dedi-
`cated processors which are equivalents to the invention as
`described and claimed: Similarly, general purpose comput-
`ers, microprocessor based computers, micro-controllers,
`optical computers, analog computers, dedicated processors
`and/or dedicated hard wired logic may be used to construct
`alternative equivalent embodiments ofthe present invention.
`Those skilled in the art will appreciate that the program
`steps and associated data used to implement the embodi-
`ments described above can be implemented using disc
`storage as well as other forms of storage such as for example
`Read Only Memory (ROM) devices, Random Access
`Memory (RAM)devices; optical storage elements, magnetic
`storage elements, magneto-optical storage elements, flash
`memory, core memory and/or other equivalent storage tech-
`nologies without departing from the present invention. Such
`alternative storage devices should be considered equiva-
`lents.

`is
`implemented using a programmed processor
`executing programming instructions
`that are broadly
`described above in flow chart form that can be stored on any
`suitable electronic storage mediumor transmitted over any
`suitable electronic communication medium. However, those
`skilled in the art will appreciate that the processes described
`above can be implemented in any numberof variations and
`in many suitable programming languages without departing
`fromthe present invention. For example, the order ofcertain
`operations carried out can often be varied, additional opera-
`tions can be added or operations can be deleted without
`departing from the invention. Error trapping can be added
`and/or enhanced andvariations can be madein userinterface

`With reference to FIG. 9, an exemplary process for a user
`associating a time zone with an event is broadly depicted as
`process 900 starting at 910. At 920, the user enters an event
`in the appropriate location on the time grid and thenselects
`a time zone at 930. In one embodiment, this is done by
`selecting a details buttonto call up a time zoneselection, and
`then selecting the time zone from a time zone menu. Once
`the time zoneis selected, it is associated with the entry and
`the eventis displayed in the currently selected display time
`zone at 940. The process ends at 950.
`With reference to FIG. 10, an exemplaryprocessfor a user
`changing the display time zone is broadly depicted as
`process 1000 starting at 1010. At 1020, the user selects a
`time zone for the display time zone. This may be accom-
`plished by selecting a time zone button from the user
`interface to produce a time zone menu or using any other
`suitable user interface mechanism. At 1030, all events to be
`displayed are translated to the display time zone. At 1040,
`the translated events are displayed in the current time zone.
`The process ends at 1050.
