unexpected result of dateFromComponents:

Question

the following code

NSCalendar *cal = [NSCalendar currentCalendar];
[cal setFirstWeekday:2];
[cal setMinimumDaysInFirstWeek:4];

NSDateComponents *comp = [[NSDate         


        

Answer 1

When you call dateFromComponents: you lose all of the timezone and calendar information and are left an NSDate object that contains the moment in time your date components represent, but nothing else. When you use NSLog on your NSDate object, that moment in time is converted to a time in UTC and rendered as a human readable string.

You need to provide more info about what you're trying to achieve to be able to answer your second question of how to avoid this.
