Class TimeZone

java.lang.Object

com.atlassian.confluence.core.TimeZone

public class TimeZone
extends Object

Represents an instance of an valid time zone, wrapping a TimeZone. Call getInstance(String) to get a specific TimeZone object.

The list of acceptable time zones is loaded once from a properties file, and trying to retrieve a time zone not in this list will return the application's default time zone.

TODO CONFDEV-27850: should be using a CacheLoader for timeZonesByID to avoid race conditions on TimeZone construction.

Method Detail

getInstance

public static TimeZone getInstance(String timeZoneID)

Returns the flyweight TimeZone for the given ID, which is the same instance used for this time zone throughout the system.

Parameters:

timeZoneID - a valid time zone ID as specified by TimeZone

Returns:

the TimeZone specified by the time zone ID, or the default time zone if timeZoneID is null or not in the list of time zones returned by getSortedTimeZones().

getInstance

public static TimeZone getInstance(TimeZone timeZone)

getID

public String getID()

Returns:

the time zone identifier as returned by TimeZone.getID().

getMessageKey

public String getMessageKey()

Returns:

a message key which can be used with ConfluenceActionSupport.getText(String) to display the localised name of the time zone.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getDisplayOffset

public String getDisplayOffset()

Returns:

the raw offset in a printable format, e.g. +0800, -1230

getDefault

@Deprecated
public static TimeZone getDefault()

Deprecated.

since 5.7. Use TimeZoneManager.getDefaultTimeZone()} instead.

This method should no longer be used. The notion of a "default timezone" is now specific to the current tenant, rather than a system level JDK concern.

Returns:

the tenant's default timezone, retrieved from TimeZoneManager.getDefaultTimeZone()}

TimeZoneManager.getDefaultTimeZone()

getSortedTimeZones

public static List<TimeZone> getSortedTimeZones()

Returns:

the list of available time zones sorted by offset from GMT (west to east), then by alphabetical order of time zone ID.

getWrappedTimeZone

public TimeZone getWrappedTimeZone()

Returns:

the underlying TimeZone which is wrapped by this implementation.
