The time on my iPhone 4 is roughly 30 seconds ahead of the time on my MacBook Pro. I can change hour/minute on my iPhone 4, but not the seconds. This difference presents itself as a minor annoyance when the calendar alerts on my iPhone 4 go off ~30 seconds before they go off on my MacBook Pro. Does anyone know how to fix this? By the way, the time on my MacBook Pro is in sync with the time server and my iPhone 4 is not.
