How to set UIDatePicker's date's seconds value to 00?

cocoa-touch, ios, nsdate, objective-c, uidatepicker

Solution

NSDate *currentDate = [datePicker date];    
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"ss"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0.0]];
NSString *Str_Seccond=[dateFormatter stringFromDate:currentDate];

In Str_Seccond string you can get the seconds in string format.

Problem

How to always get seconds value "`00`" for `UIDatePicker`'s date? Now I am getting value like this format `5:30:45`, I need to get this format of time `5:30:00`. How to achieve this?
