NSDate *now = [[NSDate alloc] init];

NSString *theDate = [dateFormat stringFromDate:now];

NSLog(@"\n"

      "theDate: |%@| \n"
      "theTime: |%@| \n"

[dateFormat release];
[timeFormat release];
[now release];

You can use NSTimer, specifically scheduledTimerWithTimeInterval:target:selector:userInfo:repeats:. You can use 1 as a time interval.
