Remarks

SimpleTimeZone is a concrete subclass of TimeZone that represents a time zone for use with a Gregorian calendar. The class holds an offset from GMT, called raw offset, and start and end rules for a daylight saving time schedule. Since it only holds single values for each, it cannot handle historical changes in the offset from GMT and the daylight saving schedule, except that the #setStartYear setStartYear method can specify the year when the daylight saving time schedule starts in effect.

To construct a SimpleTimeZone with a daylight saving time schedule, the schedule can be described with a set of rules, start-rule and end-rule. A day when daylight saving time starts or ends is specified by a combination of month, day-of-month, and day-of-week values. The month value is represented by a Calendar Calendar#MONTH MONTH field value, such as Calendar#MARCH. The day-of-week value is represented by a Calendar Calendar#DAY_OF_WEEK DAY_OF_WEEK value, such as Calendar#SUNDAY SUNDAY. The meanings of value combinations are as follows.

<ul> <li>Exact day of month To specify an exact day of month, set the month and day-of-month to an exact value, and day-of-week to zero. For example, to specify March 1, set the month to Calendar#MARCH MARCH, day-of-month to 1, and day-of-week to 0.</li>

<li>Day of week on or after day of month To specify a day of week on or after an exact day of month, set the month to an exact month value, day-of-month to the day on or after which the rule is applied, and day-of-week to a negative Calendar#DAY_OF_WEEK DAY_OF_WEEK field value. For example, to specify the second Sunday of April, set month to Calendar#APRIL APRIL, day-of-month to 8, and day-of-week to -Calendar#SUNDAY SUNDAY.</li>

<li>Day of week on or before day of month To specify a day of the week on or before an exact day of the month, set day-of-month and day-of-week to a negative value. For example, to specify the last Wednesday on or before the 21st of March, set month to Calendar#MARCH MARCH, day-of-month is -21 and day-of-week is -Calendar#WEDNESDAY WEDNESDAY. </li>

<li>Last day-of-week of month To specify, the last day-of-week of the month, set day-of-week to a Calendar#DAY_OF_WEEK DAY_OF_WEEK value and day-of-month to -1. For example, to specify the last Sunday of October, set month to Calendar#OCTOBER OCTOBER, day-of-week to Calendar#SUNDAY SUNDAY and day-of-month to -1. </li>

</ul> The time of the day at which daylight saving time starts or ends is specified by a millisecond value within the day. There are three kinds of modes to specify the time: #WALL_TIME, #STANDARD_TIME and #UTC_TIME. For example, if daylight saving time ends at 2:00 am in the wall clock time, it can be specified by 7200000 milliseconds in the #WALL_TIME mode. In this case, the wall clock time for an end-rule means the same thing as the daylight time.

The following are examples of parameters for constructing time zone objects.

<code>
                 // Base GMT offset: -8:00
                 // DST starts:      at 2:00am in standard time
                 //                  on the first Sunday in April
                 // DST ends:        at 2:00am in daylight time
                 //                  on the last Sunday in October
                 // Save:            1 hour
                 SimpleTimeZone(-28800000,
                                "America/Los_Angeles",
                                Calendar.APRIL, 1, -Calendar.SUNDAY,
                                7200000,
                                Calendar.OCTOBER, -1, Calendar.SUNDAY,
                                7200000,
                                3600000)

                 // Base GMT offset: +1:00
                 // DST starts:      at 1:00am in UTC time
                 //                  on the last Sunday in March
                 // DST ends:        at 1:00am in UTC time
                 //                  on the last Sunday in October
                 // Save:            1 hour
                 SimpleTimeZone(3600000,
                                "Europe/Paris",
                                Calendar.MARCH, -1, Calendar.SUNDAY,
                                3600000, SimpleTimeZone.UTC_TIME,
                                Calendar.OCTOBER, -1, Calendar.SUNDAY,
                                3600000, SimpleTimeZone.UTC_TIME,
                                3600000)
</code>

These parameter rules are also applicable to the set rule methods, such as setStartRule.
