Question

Im working on an app in which i want to fire local-notification on time set by user im just facing problem in getting correct time , So what im doing is this:

NSDateFormatter *current = [[NSDateFormatter alloc] init];
[current setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"]];
[current setDateFormat:@"HH:MM:SS"];
NSDate *systemTime = [NSDate date];
[current setTimeZone:[NSTimeZone systemTimeZone]];

NSLog(@"Current time %@" ,[current stringFromDate:systemTime]);
temp = [timeSetter date];//this temp is NSDATE object

NSLog(@"USer time %@" ,[current stringFromDate:temp]);
value = [temp timeIntervalSinceDate:systemTime];//This value is Nstimeinterval instance/obj.

And when im printing this through NSLog these are the results which i’ve recieved

I just ran your code, and reproduced a similar result. Your problem is with the -setDateFormat: method – it should be [current setDateFormat:@"HH:mm:ss"] – this works OK for me.
In date format strings M = month (02 = February), m = minute, S = fractions of a second and s = seconds.

If you look at the Apple documentation on date formatting, you’ll see that the format strings are determined in a Unicode standard. They link to various versions; the most recent is here
