Well, I really did not notice this really slooooooooooow fadeout of my *beautiful* scrollview shadows.

{
    NSDateFormatter *df = [[NSDateFormatter alloc] init];
    [df setDateFormat:@"yyyy-MM-dd HH:mm:ss zzz"];
    NSDate *fadeOutStartDate = [df dateFromString:@"2013-01-21 15:00:00 +0100"];
    NSDate *fadeOutEndDate = [df dateFromString:@"2013-01-25 18:00:00 +0100"];
    NSDate *now = [NSDate date];
    
    float blendValue = (now.timeIntervalSince1970 - fadeOutStartDate.timeIntervalSince1970) /
                        (fadeOutEndDate.timeIntervalSince1970 - fadeOutStartDate.timeIntervalSince1970);
    if (blendValue < 0) blendValue = 0;
    if (blendValue > 1) blendValue = 1;
    self.leftShadowView.alpha *= 1 - blendValue;
    self.rightShadowView.alpha *= 1 - blendValue;
}
