SimpleTimeZone

open class SimpleTimeZone : TimeZone

kotlin.Any
↳	java.util.TimeZone
	↳	java.util.SimpleTimeZone

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 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 MONTH field value, such as Calendar#MARCH. The day-of-week value is represented by a Calendar DAY_OF_WEEK value, such as SUNDAY. The meanings of value combinations are as follows.

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 MARCH, day-of-month to 1, and day-of-week to 0.
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 DAY_OF_WEEK field value. For example, to specify the second Sunday of April, set month to APRIL, day-of-month to 8, and day-of-week to -SUNDAY.
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 MARCH, day-of-month is -21 and day-of-week is -WEDNESDAY.
Last day-of-week of month
To specify, the last day-of-week of the month, set day-of-week to a DAY_OF_WEEK value and day-of-month to -1. For example, to specify the last Sunday of October, set month to OCTOBER, day-of-week to SUNDAY and day-of-month to -1.

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.

`endTime`	Int: The daylight saving ending time in local wall clock time, (in milliseconds within the day) which is local daylight time in this case.
`after`	Boolean: If true, this rule selects the first `endDayOfWeek` on or after `endDay`. If false, this rule selects the last `endDayOfWeek` on or before `endDay` of the month.

Exceptions
`java.lang.IllegalArgumentException`	the `endMonth`, `endDay`, `endDayOfWeek`, or `endTime` parameters are out of range

setRawOffset

Added in API level 1

open fun setRawOffset(offsetMillis: Int): Unit

Sets the base time zone offset to GMT. This is the offset to add to UTC to get local time.

Parameters
`offsetMillis`	Int: the given base time zone offset to GMT.

setStartRule

Added in API level 1

open fun setStartRule(
    startMonth: Int, 
    startDay: Int, 
    startDayOfWeek: Int, 
    startTime: Int
): Unit

Sets the daylight saving time start rule. For example, if daylight saving time starts on the first Sunday in April at 2 am in local wall clock time, you can set the start rule by calling:

<code>setStartRule(Calendar.APRIL, 1, Calendar.SUNDAY, 2*60*60*1000);</code>

Parameters
`startMonth`	Int: The daylight saving time starting month. Month is a `MONTH` field value (0-based. e.g., 0 for January).
`startDay`	Int: The day of the month on which the daylight saving time starts. See the class description for the special cases of this parameter.
`startDayOfWeek`	Int: The daylight saving time starting day-of-week. See the class description for the special cases of this parameter.
`startTime`	Int: The daylight saving time starting time in local wall clock time, which is local standard time in this case.

Exceptions
`java.lang.IllegalArgumentException`	if the `startMonth`, `startDay`, `startDayOfWeek`, or `startTime` parameters are out of range

setStartRule

Added in API level 1

open fun setStartRule(
    startMonth: Int, 
    startDay: Int, 
    startTime: Int
): Unit

Sets the daylight saving time start rule to a fixed date within a month. This method is equivalent to:

<code>setStartRule(startMonth, startDay, 0, startTime)</code>

Parameters
`startMonth`	Int: The daylight saving time starting month. Month is a `MONTH` field value (0-based. e.g., 0 for January).
`startDay`	Int: The day of the month on which the daylight saving time starts.
`startTime`	Int: The daylight saving time starting time in local wall clock time, which is local standard time in this case. See the class description for the special cases of this parameter.

Exceptions
`java.lang.IllegalArgumentException`	if the `startMonth`, `startDayOfMonth`, or `startTime` parameters are out of range

setStartRule

Added in API level 1

open fun setStartRule(
    startMonth: Int, 
    startDay: Int, 
    startDayOfWeek: Int, 
    startTime: Int, 
    after: Boolean
): Unit

Sets the daylight saving time start rule to a weekday before or after the given date within a month, e.g., the first Monday on or after the 8th.

Parameters
`startMonth`	Int: The daylight saving time starting month. Month is a `MONTH` field value (0-based. e.g., 0 for January).
`startDay`	Int: The day of the month on which the daylight saving time starts.
`startDayOfWeek`	Int: The daylight saving time starting day-of-week.
`startTime`	Int: The daylight saving time starting time in local wall clock time, which is local standard time in this case.
`after`	Boolean: If true, this rule selects the first `dayOfWeek` on or after `dayOfMonth`. If false, this rule selects the last `dayOfWeek` on or before `dayOfMonth`.

Exceptions
`java.lang.IllegalArgumentException`	if the `startMonth`, `startDay`, `startDayOfWeek`, or `startTime` parameters are out of range

Added in API level 1

open fun setStartYear(year: Int): Unit

Sets the daylight saving time starting year.

Parameters
