目标C-如何使用NSTimeZone获取原始偏移量(无DST) [英] Objective C - How to get raw offset (without DST) using NSTimeZone

问题描述

我想从格林尼治标准时间(GMT)获得原始补偿.我知道答案可能是这样的:

I'd like to get raw offset from GMT. I know the answer could be like that:

NSTimeZone *zone = [NSTimeZone timeZoneWithName:@"Europe/Berlin"];
NSInteger *offset = [zone secondsFromGMT];

(例如此处: iOS-如何获取时区的原始偏移量?)

但是问题是，它没有给我原始偏移量(对于柏林+1)，而只有 DST偏移量(+ 2)，也就是说，当前日期.

But the problem is, it doesn't give me raw offset (for Berlin +1), but only offset with DST (+2), that is, for the current date.

推荐答案

NSTimeZone具有属性daylightSavingTimeOffset，该属性将差值返回到原始偏移量

NSTimeZone has a property daylightSavingTimeOffset which returns the difference to the raw offset

NSTimeZone *zone = [NSTimeZone timeZoneWithName:@"Europe/Berlin"];
NSTimeInterval rawOffset = [zone secondsFromGMT] - [zone daylightSavingTimeOffset];
