Remarks
This represents a timer, a stopwatch, or a countdown to an event.
When representing a running timer (or stopwatch, etc), this value specifies a reference instant for when that timer will hit zero (or the stopwatch was at zero, respectively), called the "zero time". In this case the time displayed is defined as the difference between the "zero time" and the current time, meaning it will show a live-updated timer.
The zero time can be specified as an Instant (in which case it corresponds to a "real-world" point in time, from InstantSource.system), or as milliseconds since boot (from SystemClock.elapsedRealtime()). The latter might be suitable when the timer is tied to an AlarmManager.ELAPSED_REALTIME alarm in AlarmManager.
When representing a paused timer (or stopwatch, etc), this value specifies the duration as a fixed value.
This value can also specify its formatting, whether as a "chronometer" (e.g. 43:21) or an adaptive time (e.g. 1h 43m).

Formatting option for the timer/stopwatch. |
| Handle |

| IsStopwatch |
Whether this TimeDifference value represents a stopwatch -- when running, it counts up from getZeroTime() (or getZeroElapsedRealtime()). |
| IsTimer |
Whether this TimeDifference value represents a timer -- when running, it counts down to getZeroTime() (or getZeroElapsedRealtime()). |
| JniIdentityHashCode |
Gets the identity hash code assigned to this Java peer by the interop runtime. (Inherited from Object) |
| JniManagedPeerState |
Gets the state flags last assigned by the runtime. (Inherited from JavaObject) |
| JniPeerMembers |
Gets the JNI metadata used to access members of this Java binding. |
| PausedDuration |
The fixed time difference, for a paused timer or stopwatch. |
| PeerReference |
Gets the JNI object reference for this Java peer. (Inherited from Object) |
| ThresholdClass |
Gets the Java class used for virtual method dispatch. (Inherited from Notification.Metric.MetricValue) |
| ThresholdType |
Gets the managed type that declares this Java binding. (Inherited from Notification.Metric.MetricValue) |
| ZeroElapsedRealtime |
The elapsed realtime at which the time difference is zero. |
| ZeroTime |
The Instant at which the time difference is zero. |
