This in fact isn't such a big problem. But to get the max efficiency out of it
do it like this:

// if we're not the currently displayed app this method immediately returns
- (void) invokedOnceAMinute
{
  if ([NSApp isActive])
    {
      [self updateClockDisplay];
    }
}

// update the clock's display in case it hasn't been updated in the mean time
- (void) appDidBecomeActive
{
  [self updateClockDisplay];
}
