Olson time zones change - * behavior over time. The raw offset, rules, presence or absence of - * daylight savings time, and even the daylight savings amount can all - * vary. - * - * This class uses a resource bundle named "zoneinfo". Zoneinfo is a - * table containing different kinds of resources. In several places, - * zones are referred to using integers. A zone's integer is a number - * from 0..n-1, where n is the number of zones, with the zones sorted - * in lexicographic order. - * - * 1. Zones. These have keys corresponding to the Olson IDs, e.g., - * "Asia/Shanghai". Each resource describes the behavior of the given - * zone. Zones come in two different formats. - * - * a. Zone (table). A zone is a table resource contains several - * type of resources below: - * - * - typeOffsets:intvector (Required) - * - * Sets of UTC raw/dst offset pairs in seconds. Entries at - * 2n represents raw offset and 2n+1 represents dst offset - * paired with the raw offset at 2n. The very first pair represents - * the initial zone offset (before the first transition) always. - * - * - trans:intvector (Optional) - * - * List of transition times represented by 32bit seconds from the - * epoch (1970-01-01T00:00Z) in ascending order. - * - * - transPre32/transPost32:intvector (Optional) - * - * List of transition times before/after 32bit minimum seconds. - * Each time is represented by a pair of 32bit integer. - * - * - typeMap:bin (Optional) - * - * Array of bytes representing the mapping between each transition - * time (transPre32/trans/transPost32) and its corresponding offset - * data (typeOffsets). - * - * - finalRule:string (Optional) - * - * If a recurrent transition rule is applicable to a zone forever - * after the final transition time, finalRule represents the rule - * in Rules data. - * - * - finalRaw:int (Optional) - * - * When finalRule is available, finalRaw is required and specifies - * the raw (base) offset of the rule. - * - * - finalYear:int (Optional) - * - * When finalRule is available, finalYear is required and specifies - * the start year of the rule. - * - * - links:intvector (Optional) - * - * When this zone data is shared with other zones, links specifies - * all zones including the zone itself. Each zone is referenced by - * integer index. - * - * b. Link (int, length 1). A link zone is an int resource. The - * integer is the zone number of the target zone. The key of this - * resource is an alternate name for the target zone. This data - * is corresponding to Link data in the tz database. - * - * - * 2. Rules. These have keys corresponding to the Olson rule IDs, - * with an underscore prepended, e.g., "_EU". Each resource describes - * the behavior of the given rule using an intvector, containing the - * onset list, the cessation list, and the DST savings. The onset and - * cessation lists consist of the month, dowim, dow, time, and time - * mode. The end result is that the 11 integers describing the rule - * can be passed directly into the SimpleTimeZone 13-argument - * constructor (the other two arguments will be the raw offset, taken - * from the complex zone element 5, and the ID string, which is not - * used), with the times and the DST savings multiplied by 1000 to - * scale from seconds to milliseconds. - * - * 3. Regions. An array specifies mapping between zones and regions. - * Each item is either a 2-letter ISO country code or "001" - * (UN M.49 - World). This data is generated from "zone.tab" - * in the tz database. - */ -class U_I18N_API OlsonTimeZone: public BasicTimeZone { - public: - /** - * Construct from a resource bundle. - * @param top the top-level zoneinfo resource bundle.
