Hi
 I'm trying to make a simple clock which is generated in a text field by
clicking a button.
 //This code is supposed to trigger the clock
NSDate *today = [NSDate date];
[showTime setStringValue:today];
 While it does generate the current date and time, it fails to update it -
and here's where my Obj-C experience fails me.
How do I go about to update the textfield?
 I did some research and found out that one way to do it is by implementing
this code:
//from http://www.cocoabuilder.com/archive/message/cocoa/2003/7/7/3275
NSTimer *timer = [[NSTimer alloc] initWithFireDate:startTime
interval:1.0 target:self selector:@selector(update:) userInfo:nil
repeats:YES];
 But since I'm a Obj-C beginner I'm having a hard time using it in my own
little application.
Can someone give me a couple of pointers on how this specific task is to be
dealt with?
 Best regards
