Remarks

TimeZone represents a time zone offset, and also figures out daylight savings.

Typically, you get a TimeZone using getDefault which creates a TimeZone based on the time zone where the program is running. For example, for a program running in Japan, getDefault creates a TimeZone object based on Japanese Standard Time.

You can also get a TimeZone using getTimeZone along with a time zone ID. For instance, the time zone ID for the U.S. Pacific Time zone is "America/Los_Angeles". So, you can get a U.S. Pacific Time TimeZone object with: <blockquote> {

Constructors

Name	Description
TimeZone()	Sole constructor.
TimeZone(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

Name	Description
Long	Obsolete. A style specifier for `getDisplayName()` indicating a long name, such as "Pacific Standard Time.
Short	Obsolete. A style specifier for `getDisplayName()` indicating a short name, such as "PST.

Properties

Name	Description
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Default	Gets the default `TimeZone` for this host. -or- Sets the `TimeZone` that is returned by the `getDefault` method.
DisplayName	Returns a long standard time name of this `TimeZone` suitable for presentation to the user in the default locale.
DSTSavings	Returns the amount of time to be added to local standard time to get local wall clock time.
Handle	The handle to the underlying Android instance. (Inherited from Object)
ID	Gets the ID of this time zone. -or- Sets the time zone ID.
JniIdentityHashCode	Gets the identity hash code assigned to this Java peer by the interop runtime. (Inherited from Object)
JniPeerMembers
PeerReference	Gets the JNI object reference for this Java peer. (Inherited from Object)
RawOffset	Returns the offset in milliseconds from UTC of this time zone's standard time.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

Name	Description
Clone()	Creates a copy of this `TimeZone`.
Dispose()	Releases the resources held by this Java peer. (Inherited from Object)
Dispose(Boolean)	Releases the resources held by this Java peer. (Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetAvailableIDs()	Gets all the available IDs supported.
GetAvailableIDs(Int32)	Gets the available IDs according to the given time zone offset in milliseconds.
GetDisplayName(Boolean, TimeZoneStyle, Locale)	Returns the `#SHORT short` or `#LONG long` name of this time zone with either standard or daylight time, as written in `locale`.
GetDisplayName(Boolean, TimeZoneStyle)	Returns a name in the specified `style` of this `TimeZone` suitable for presentation to the user in the default locale.

GetTimeZone(String)	Gets the `TimeZone` for the given ID.
GetTimeZone(ZoneId)	Gets the `TimeZone` for the given `zoneId`.
HasSameRules(TimeZone)	Returns true if this zone has the same rule and offset as another zone.
InDaylightTime(Date)	Queries if the given `date` is in Daylight Saving Time in this time zone.

ToString()	Returns a string representation of the object. (Inherited from Object)
ToZoneId()	Converts this `TimeZone` object to a `ZoneId`.
UnregisterFromRuntime()	Unregisters this Java peer from the interop runtime. (Inherited from Object)
UseDaylightTime()	Queries if this `TimeZone` uses Daylight Saving Time.
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
