Central +to this is the concept of "time bounds". Views in Open MCT will typically show +telemetry data for some prescribed date range, and the Time API provides a way +to centrally manage these bounds. + +The Time API exposes a number of methods for querying and setting the temporal +state of the application, and emits events to inform listeners when the state changes. + +Because the data displayed tends to be time domain data, Open MCT must always +have at least one time system installed and activated. When you download Open MCT, +it will be pre-configured to use the UTC time system, which is installed and +activated, along with other default plugins, in `index.html`. Installing and +activating a time system is simple, and is covered +[in the next section](#defining-and-registering-time-systems). + +### Time Systems and Bounds +#### Defining and Registering Time Systems +The time bounds of an Open MCT application are defined as numbers, and a Time +System gives meaning and context to these numbers so that they can be correctly +interpreted. Time Systems are javscript objects that provide some information +about the current time reference frame. An example of defining and registering +a new time system is given below: + +``` javascript +openmct.time.addTimeSystem({ + key: 'utc', + name: 'UTC Time', + cssClass = 'icon-clock', + timeFormat = 'utc', + durationFormat = 'duration', + isUTCBased = true +}); +``` + +The example above defines a new utc based time system. In fact, this time system +is configured and activated by default from `index.html` in the default +installation of Open MCT if you download the source from GitHub. Some details of +each of the required properties is provided below. + +* `key`: A `string` that uniquely identifies this time system. +* `name`: A `string` providing a brief human readable label. If the [Time Conductor](#the-time-conductor) +plugin is enabled, this name will identify the time system in a dropdown menu. +* `cssClass`: A class name `string` that will be applied to the time system when +it appears in the UI. This will be used to represent the time system with an icon. +There are a number of built-in icon classes [available in Open MCT](https://github.com/nasa/openmct/blob/master/platform/commonUI/general/res/sass/_glyphs.scss), +or a custom class can be used here. +* `timeFormat`: A `string` corresponding to the key of a registered +[telemetry time format](#telemetry-formats). The format will be used for +displaying discrete timestamps from telemetry streams when this time system is +activated. If the [UTCTimeSystem](#included-plugins) is enabled, then the `utc` +format can be used if this is a utc-based time system +* `durationFormat`: A `string` corresponding to the key of a registered +[telemetry time format](#telemetry-formats). The format will be used for +displaying time ranges, for example `00:15:00` might be used to represent a time +period of fifteen minutes. These are used by the Time Conductor plugin to specify +relative time offsets. If the [UTCTimeSystem](#included-plugins) is enabled, +then the `duration` format can be used if this is a utc-based time system +* `isUTCBased`: A `boolean` that defines whether this time system represents +numbers in UTC terrestrial time. + +#### Getting and Setting the Active Time System + +Once registered, a time system can be activated using a key, or an instance of +the time system itself. + +```javascript +openmct.time.timeSystem('utc'); +``` + +A time system can be immediately activated upon registration: + +```javascript +var utcTimeSystem = { + key: 'utc', + name: 'UTC Time', + cssClass = 'icon-clock', + timeFormat = 'utc', + durationFormat = 'duration', + isUTCBased = true +}; +openmct.time.addTimeSystem(utcTimeSystem); +openmct.time.timeSystem(utcTimeSystem); +``` + +Setting the active time system will trigger a [time system event](#time-events). + +### Time Bounds + +The TimeAPI provides a getter/setter for querying and setting time bounds. Time +bounds are simply an object with a `start` and an end `end` attribute. + +* `start`: A `number` representing a moment in time in the active [Time System](#defining-and-registering-time-systems). +This will be used as the beginning of the time period displayed by time-responsive +telemetry views. +* `end`: A `number` representing a moment in time in the active [Time System](#defining-and-registering-time-systems). +This will be used as the end of the time period displayed by time-responsive +telemetry views. + +If invoked with bounds, it will set the new time bounds system-wide. If invoked +without any parameters, it will return the current application-wide time bounds. + +``` javascript +const ONE_HOUR = 60 * 60 * 1000; +let now = Date.now(); +openmct.time.bounds({start: now - ONE_HOUR, now); +``` + +To respond to bounds change events, simply register a callback against the `bounds` +event. For more information on the bounds event, please see the section on [Time Events](#time-events). + +## Clocks + +The Time API can be set to follow a clock source which will cause the bounds +to be updated automatically whenever the clock source "ticks". A clock is simply +an object that supports registration of listeners and periodically invokes its +listeners with a number. Open MCT supports registration of new clock sources that +tick on almost anything. A tick occurs when the clock invokes callback functions +registered by its listeners with a new time value. + +An example of a clock source is the [LocalClock](https://github.com/nasa/openmct/blob/master/src/plugins/utcTimeSystem/LocalClock.js) +which emits the current time in UTC every 100ms. Clocks can tick on anything. For +example, a clock could be defined to provide the timestamp of any new data +received via a telemetry subscription. This would have the effect of advancing +the bounds of views automatically whenever data is received. A clock could also +be defined to tick on some remote timing source. + +The values provided by clocks are simple `number`s, which are interpreted in the +context of the active [Time System](#defining-and-registering-time-systems). + +### Defining and registering clocks +A clock is an object that defines certain required metadata and functions: + +* `key`: A `string` uniquely identifying this clock. This can be used later to +reference the clock in places such as the [Time Conductor configuration](#time-conductor-configuration) +* `cssClass`: A `string` identifying a CSS class to apply to this clock when it's +displayed in the UI. This will be used to represent the time system with an icon. +There are a number of built-in icon classes [available in Open MCT](https://github.com/nasa/openmct/blob/master/platform/commonUI/general/res/sass/_glyphs.scss), +or a custom class can be used here. +* `name`: A `string` providing a human-readable identifier for the clock source. +This will be displayed in the clock selector menu in the Time Conductor UI +component, if active. +* `description`: An __optional__ `string` providing a longer description of the +clock. The description will be visible in the clock selection menu in the Time +Conductor plugin. +* `on`: A `function` supporting registration of a new callback that will be +invoked when the clock next ticks. It will be invoked with two arguments: + * `eventName`: A `string` specifying the event to listen on. For now, clocks + support one event - `tick`. + * `callback`: A `function` that will be invoked when this clock ticks. The + function must be invoked with one parameter - a `number` representing a valid + time in the current time system. +* `off`: A `function` that allows deregistration of a tick listener. It accepts +the same arguments as `on`. +* `currentValue`: A `function` that returns a `number` representing a point in +time in the active time system. It should be the last value provided by a tick, +or some default value if no ticking has yet occurred. + +A new clock can be registered using the `addClock` function exposed by the Time +API: + +```javascript +var someClock = { + key: 'someClock', + cssClass: 'icon-clock', + name: 'Some clock', + description: "Presumably does something useful", + on: function (event, callback) { + // Some function that registers listeners, and updates them on a tick + }, + off: function (event, callback) { + // Some function that unregisters listeners. + }, + currentValue: function () { + // A function that returns the last ticked value for the clock + } +} + +openmct.time.addClock(someClock); +``` + +An example clock implementation is provided in the form of the [LocalClock](https://github.com/nasa/openmct/blob/master/src/plugins/utcTimeSystem/LocalClock.js) + +#### Getting and setting active clock + +Once registered a clock can be activated by calling the `clock` function on the +Time API passing in the key or instance of a registered clock. Only one clock +may be active at once, so activating a clock will deactivate any currently +active clock. Setting the clock will also trigger a ['clock' event](#time-events). + +``` +openmct.time.clock(someClock); +``` + +Upon being activated, a clock's `on` function will be immediately called to subscribe +to `tick` events. + +The currently active clock (if any) can be retrieved by calling the same +function without any arguments. + +#### Stopping an active clock + +The `stopClock` method can be used to stop an active clock, and to clear it. It +will stop the clock from ticking, and set the active clock to `undefined`. + +``` javascript +openmct.time.stopClock(); +``` + +#### Clock Offsets + +When a clock is active, the time bounds of the application will be updated +automatically each time the clock "ticks". The bounds are calculated based on +the current value provided by the active clock (via its `tick` event, or its +`currentValue()` method). + +Unlike bounds, which represent absolute time values, clock offsets represent +relative time spans. Offsets are defined as an object with two properties: + +* `start`: A `number` that must be < 0 and which is used to calculate the start +bounds on each clock tick. The start offset will be calculated relative to the +value provided by a clock's tick callback, or its `currentValue()` function. +* `end`: A `number` that must be >=0 and which is used to calculate the end +bounds on each clock tick. + +The `clockOffsets` function can be used to get or set clock offsets. For example, +to show the last fifteen minutes in a ms-based time system: + +```javascript +var FIFTEEN_MINUTES = 15 * 60 * 1000; + +openmct.time.clockOffsets({ + start: -FIFTEEN_MINUTES, + end: 0 +}) +``` + +__Note:__ Setting the clock offsets will trigger an immediate bounds change, as +new bounds will be calculated based on the `currentValue()` of the active clock. +Clock offsets are only relevant when a clock source is active. + +## Time Events +The time API supports the registration of listeners that will be invoked when the +application's temporal state changes. Events listeners can be registered using +the `on` function. They can be deregistered using the `off` function. The arguments +accepted by the `on` and `off` functions are: + +* `event`: A `string` naming the event to subscribe to. Event names correspond to +the property of the Time API you're interested in. A [full list of time events](#list-of-time-events) +is provided later. + +As an example, the code to listen to bounds change events looks like: + +``` javascript +openmct.time.on('bounds', function callback (newBounds, tick) { + // Do something with new bounds +}); +``` + +#### List of Time Events +The events supported by the Time API are: + +* `bounds`: Listen for changes to current bounds. The callback will be invoked +with two arguments: + * `bounds`: A [bounds](#getting-and-setting-bounds) bounds object representing + a new time period bound by the specified start and send times. + * `tick`: A `boolean` indicating whether or not this bounds change is due to a + "tick" from a [clock source](#clocks). This information can be useful when + determining a strategy for fetching telemetry data in response to a bounds + change event. For example, if the bounds change was automatic, and is due + to a tick then it's unlikely that you would need to perform a historical + data query. It should be sufficient to just show any new telemetry received + via subscription since the last tick, and optionally to discard any older + data that now falls outside of the currently set bounds. If `tick` is false, + then the bounds change was not due to an automatic tick, and a query for + historical data may be necessary, depending on your data caching strategy, + and how significantly the start bound has changed. +* `timeSystem`: Listen for changes to the active [time system](#defining-and-registering-time-systems). +The callback will be invoked with a single argument - the newly active time system. + * `timeSystem`: The newly active [time system](#defining-and-registering-time-systems) object. +* `clock`: Listen for changes to the active clock. When invoked, the callback +will be provided with the new clock. + * `clock`: The newly active [clock](#clocks), or `undefined` if an active clock + has been deactivated. +* `clockOffsets`: Listen for changes to active clock offsets. When invoked the +callback will be provided with the new clock offsets. + * `clockOffsets`: A [clock offsets](#clock-offsets) object. + + +## The Time Conductor +The Time Conductor provides a user interface for managing time bounds in Open MCT. +It allows a user to select from configured time systems and clocks, and to set bounds +and clock offsets. + +If activated, the time conductor must be provided with configuration options, +detailed below. + +#### Time Conductor Configuration +The time conductor is configured by specifying the options that will be +available to the user from the menus in the time conductor. These will determine +the clocks available from the conductor, the time systems available for each +clock, and some default bounds and clock offsets for each combination of clock +and time system. By default, the conductor always supports a `fixed` mode where +no clock is active. To specify configuration for fixed mode, simply leave out a +`clock` attribute in the configuration entry object. + +Configuration is provided as an `array` of menu options. Each entry of the +array is an object with some properties specifying configuration. The configuration +options specified are slightly different depending on whether or not it is for +an active clock mode. + +__Configuration for Fixed Time Mode (no active clock)__ + +* `timeSystem`: A `string`, the key for the time system that this configuration +relates to. +* `bounds`: A [`Time Bounds`](#time-bounds) object. These bounds will be applied +when the user selects the time system specified in the previous `timeSystem` +property. +* `zoomOutLimit`: An __optional__ `number` specifying the longest period of time +that can be represented by the conductor when zooming. If a `zoomOutLimit` is +provided, then a `zoomInLimit` must also be provided. If provided, the zoom +slider will automatically become available in the Time Conductor UI. +* `zoomInLimit`: An __optional__ `number` specifying the shortest period of time +that can be represented by the conductor when zooming. If a `zoomInLimit` is +provided, then a `zoomOutLimit` must also be provided. If provided, the zoom +slider will automatically become available in the Time Conductor UI. + +__Configuration for Active Clock__ + +* `clock`: A `string`, the `key` of the clock that this configuration applies to. +* `timeSystem`: A `string`, the key for the time system that this configuration +relates to. Separate configuration must be provided for each time system that you +wish to be available to users when they select the specified clock. +* `clockOffsets`: A [`clockOffsets`](#clock-offsets) object that will be +automatically applied when the combination of clock and time system specified in +this configuration is selected from the UI. + +#### Example conductor configuration +An example time conductor configuration is provided below. It sets up some +default options for the [UTCTimeSystem](https://github.com/nasa/openmct/blob/master/src/plugins/utcTimeSystem/UTCTimeSystem.js) +and [LocalTimeSystem](https://github.com/nasa/openmct/blob/master/src/plugins/localTimeSystem/LocalTimeSystem.js), +in both fixed mode, and for the [LocalClock](https://github.com/nasa/openmct/blob/master/src/plugins/utcTimeSystem/LocalClock.js) +source. In this configutation, the local clock supports both the UTCTimeSystem +and LocalTimeSystem. Configuration for fixed bounds mode is specified by omitting +a clock key. + +``` javascript +const ONE_YEAR = 365 * 24 * 60 * 60 * 1000; +const ONE_MINUTE = 60 * 1000; + +openmct.install(openmct.plugins.Conductor({ + menuOptions: [ + // 'Fixed' bounds mode configuation for the UTCTimeSystem + { + timeSystem: 'utc', + bounds: {start: Date.now() - 30 * ONE_MINUTE, end: Date.now()}, + zoomOutLimit: ONE_YEAR, + zoomInLimit: ONE_MINUTE + }, + // Configuration for the LocalClock in the UTC time system + { + clock: 'local', + timeSystem: 'utc', + clockOffsets: {start: - 30 * ONE_MINUTE, end: 0}, + zoomOutLimit: ONE_YEAR, + zoomInLimit: ONE_MINUTE + }, + //Configuration for the LocaLClock in the Local time system + { + clock: 'local', + timeSystem: 'local', + clockOffsets: {start: - 15 * ONE_MINUTE, end: 0} + } + ] +})); +``` + ## Included Plugins Open MCT is packaged along with a few general-purpose plugins: +* `openmct.plugins.Conductor` provides a user interface for working with time +within the application. If activated, configuration must be provided. This is +detailed in the section on [Time Conductor Configuration](#time-conductor-configuration). * `openmct.plugins.CouchDB` is an adapter for using CouchDB for persistence of user-created objects. This is a constructor that takes the URL for the CouchDB database as a parameter, e.g. diff --git a/example/localTimeSystem/src/LocalTimeSystem.js b/example/localTimeSystem/src/LocalTimeSystem.js deleted file mode 100644 index ee309d09b0..0000000000 --- a/example/localTimeSystem/src/LocalTimeSystem.js +++ /dev/null @@ -1,79 +0,0 @@ -/***************************************************************************** - * Open MCT Web, Copyright (c) 2014-2015, United States Government - * as represented by the Administrator of the National Aeronautics and Space - * Administration.
