I am having trouble with the clock syncing among my Macbook pro (running 10.6.4), my iphone 4, and my iPad. All three are set to "set automatically". Yet when I have an event with an alarm, my iPad rings, then 20 seconds later it's my MBP, then 10 seconds later it's my iphone. I know it's a small gripe, but it's annoying. These used to all happen at the same time. Any way to "push" the correct time to these? Thanks.
