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.

  Parameters:
    `date` - the date to check
  Returns:
    offset amount

### getGMTString

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

  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

### getOffset

    int getOffset(java.util.Date date)

  Returns the RFC representation of the time zone name for the given date. To be consistent with JDK/Javascript API, west of Greenwich will be positive.

  Parameters:
    `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
  Returns:
    true if daylight savings time is in effect
