public class SimpleTimeZone
extends TimeZone

`SimpleTimeZone` is a concrete subclass of `TimeZone` that represents a time zone for use with a Gregorian calendar. This simple class does not handle historical changes, and has limited rules.

Use a negative value for `dayOfWeekInMonth` to indicate that `SimpleTimeZone` should count from the end of the month backwards. For example, Daylight Savings Time ends at the last (dayOfWeekInMonth = -1) Sunday in October, at 2 AM in standard time.

SimpleTimeZone

     public SimpleTimeZone(int rawOffset,
                           String ID)

  Constructs a SimpleTimeZone with the given base time zone offset from GMT and time zone ID. Timezone IDs can be obtained from TimeZone.getAvailableIDs. Normally you should use TimeZone.getDefault to construct a TimeZone.

  Parameters:
    rawOffset - the given base time zone offset to GMT.
    ID - the time zone ID which is obtained from TimeZone.getAvailableIDs.

SimpleTimeZone

     public SimpleTimeZone(int rawOffset,
                           String ID,
                           int startMonth,
                           int startDayOfWeekInMonth,
                           int startDayOfWeek,
                           int startTime,
                           int endMonth,
                           int endDayOfWeekInMonth,
                           int endDayOfWeek,
                           int endTime)

  Constructs a SimpleTimeZone with the given base time zone offset from GMT, time zone ID, time to start and end the daylight time. Timezone IDs can be obtained from TimeZone.getAvailableIDs. Normally you should use TimeZone.getDefault to create a TimeZone. For a time zone that does not use daylight saving time, do not use this constructor; instead you should use SimpleTimeZone(rawOffset, ID).

  Parameters:
    rawOffset - the given base time zone offset to GMT.
    ID - the time zone ID which is obtained from TimeZone.getAvailableIDs.
    startMonth - the daylight savings starting month. Month is 0-based. eg, 0 for January.
    startDayOfWeekInMonth - the daylight savings starting day-of-week-in-month. Please see the member description for an example.
    startDayOfWeek - the daylight savings starting day-of-week. Please see the member description for an example.
    startTime - the daylight savings starting time. Please see the member description for an example.
    endMonth - the daylight savings ending month. Month is 0-based. eg, 0 for January.
    endDayOfWeekInMonth - the daylight savings ending day-of-week-in-month. Please see the member description for an example.
    endDayOfWeek - the daylight savings ending day-of-week. Please see the member description for an example.
    endTime - the daylight savings ending time. Please see the member description for an example.

setStartYear

     public void setStartYear(int year)

  Sets the daylight savings starting year.

  Parameters:
    year - the daylight savings starting year.

setStartRule

     public void setStartRule(int month,
                              int dayOfWeekInMonth,
                              int dayOfWeek,
                              int time)

  Sets the daylight savings starting rule. For example, Daylight Savings Time starts at the first Sunday in April, at 2 AM in standard time. Therefore, you can set the start rule by calling: setStartRule(TimeFields.APRIL, 1, TimeFields.SUNDAY, 2*60*60*1000);

  Parameters:
    month - the daylight savings starting month. Month is 0-based. eg, 0 for January.
    dayOfWeekInMonth - the daylight savings starting day-of-week-in-month. Please see the member description for an example.
    dayOfWeek - the daylight savings starting day-of-week. Please see the member description for an example.
    time - the daylight savings starting time. Please see the member description for an example.

setEndRule

     public void setEndRule(int month,
                            int dayOfWeekInMonth,
                            int dayOfWeek,
                            int time)

  Sets the daylight savings ending rule. For example, Daylight Savings Time ends at the last (-1) Sunday in October, at 2 AM in standard time. Therefore, you can set the end rule by calling: setEndRule(TimeFields.OCTOBER, -1, TimeFields.SUNDAY, 2*60*60*1000);

  Parameters:
    month - the daylight savings ending month. Month is 0-based. eg, 0 for January.
    dayOfWeekInMonth - the daylight savings ending day-of-week-in-month. Please see the member description for an example.
    dayOfWeek - the daylight savings ending day-of-week. Please see the member description for an example.
    time - the daylight savings ending time. Please see the member description for an example.
