Method Detail

getDaylightAdjustment

int getDaylightAdjustment(java.util.Date date)

Returns the daylight savings time adjustment, in minutes, for the given date. If daylight savings time is in effect on the given date, the number will be positive, otherwise 0.

Returns the GMT representation of this time zone object.

Parameters:

date - The date from which the time information should be extracted

Returns:

A GMT representation of the time given by the date

getID

java.lang.String getID()

Returns time zone id for this time zone. For time zone objects that have been instantiated from a time zone offset, the POSIX time zone id will be returned.

Returns:

time zone id

getISOTimeZoneString

java.lang.String getISOTimeZoneString(java.util.Date date)

To get ISO-style (+00:00) representation of the time zone for given date.

Parameters:

date - The date for which time to retrieve RFC time zone string

Returns:

ISO-style time zone string

getLongName

java.lang.String getLongName(java.util.Date date)

Returns the long version of the time zone name for the given date; the result of this method will be different if daylight savings time is in effect.

Parameters:

date - The date for which the long time zone name is returned

Returns:

long time zone name

date - The date for which time to retrieve time zone offset

Returns:

time zone offset in minutes

getRFCTimeZoneString

java.lang.String getRFCTimeZoneString(java.util.Date date)

To get RFC representation of certain time zone name for given date.

Parameters:

date - The date for which time to retrieve RFC time zone string

Returns:

RFC time zone string

getShortName

java.lang.String getShortName(java.util.Date date)

Returns the short time zone name for a given date.

Parameters:

date - The date for which time to retrieve short time zone

Returns:

short time zone name

getStandardOffset

int getStandardOffset()

Returns the standard time zone offset, in minutes.

isDaylightTime

boolean isDaylightTime(java.util.Date date)

Check whether the given date and time falls within a daylight savings time period.

Parameters:

date - and time to check
