@interface NSTimeZone (NSExtendedTimeZone)

+ (NSTimeZone *)systemTimeZone; 系统时区

+ (void)resetSystemTimeZone;

+ (NSTimeZone *)defaultTimeZone; 默认时区

+ (void)setDefaultTimeZone:(NSTimeZone *)aTimeZone;

+ (NSTimeZone *)localTimeZone; 本地时区

+ (NSArray *)knownTimeZoneNames;

    NSArray *arr = NSTimeZone.knownTimeZoneNames;
    
    for (NSUInteger a = 0; a < arr.count; a++) {
        NSLog(@"%@",[arr objectAtIndex:a]);
        
    }

+ (NSDictionary *)abbreviationDictionary;

+ (void)setAbbreviationDictionary:(NSDictionary *)dict NS_AVAILABLE(10_6, 4_0);

    NSDictionary *dic = NSTimeZone.abbreviationDictionary;
    NSLog(@"%@",dic);

+ (NSString *)timeZoneDataVersion NS_AVAILABLE(10_6, 4_0);

    NSString *string = NSTimeZone.timeZoneDataVersion;

@property (readonly) NSInteger secondsFromGMT; 时差

@property (readonly, copy) NSString *abbreviation; 简称

@property (readonly, getter=isDaylightSavingTime) BOOL daylightSavingTime; 夏时令

@property (readonly) NSTimeInterval daylightSavingTimeOffset NS_AVAILABLE(10_5, 2_0); //

@property (readonly, copy) NSDate *nextDaylightSavingTimeTransition NS_AVAILABLE(10_5, 2_0); //

@property (readonly, copy) NSString *description;

是否一致

- (BOOL)isEqualToTimeZone:(NSTimeZone *)aTimeZone;

typedef NS_ENUM(NSInteger, NSTimeZoneNameStyle) {

NSTimeZoneNameStyleStandard, // Central Standard Time

NSTimeZoneNameStyleShortStandard, // CST

NSTimeZoneNameStyleDaylightSaving, // Central Daylight Time

NSTimeZoneNameStyleShortDaylightSaving, // CDT

NSTimeZoneNameStyleGeneric, // Central Time

NSTimeZoneNameStyleShortGeneric // CT

};

- (NSString *)localizedName:(NSTimeZoneNameStyle)style locale:(NSLocale *)locale NS_AVAILABLE(10_5, 2_0);
