Time zone in swift - NSDate

i'm using xCode 7.2.1 ad Swift2, writing fo iOS.

i did a function for converting a String to a NSDate and that's :

class func StringToDateWithHour(data : String) -> NSDate { let dateFormatter = NSDateFormatter() dateFormatter.timeZone = NSTimeZone(abbreviation: "CET"); dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss" guard let date = dateFormatter.dateFromString(data) else{ return NSDate() } return date }

I don't understand why i get back the UTC time, INSTEAD of CET time. When i try to convert a string like : "2016-2-21 10:00:00" i get back "2016-2-21 09:00:00" , one hour less. Thank you.

You're saying that you want to convert 10 am CET to a NSDate. That correctly outputs 9 am UTC time (UTC is one hour behind CET time).

NSDate objects don't depend on time zones, they're just data from a particular point in time.

NSDate objects encapsulate a single point in time, independent of any particular calendrical system or time zone. Date objects are immutable, representing an invariant time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001).
