Official Start Time Confirmation:
Diana Nyad began her 103-mile adventure on the Caribbean Sea at 7:30 pm New York time this evening.
With Cuban officials and supporters lining the beach and a CNN crew on hand to record the historic occasion, Diana will begin later tonight.
Assuming a 60-hour swim, she will finish at 2:00 am New York time on Wednesday early morning.
So she will swim through Sunday night, Monday day and night, Tuesday day and night, with a finish somewhere along the Florida Keys on early Wednesday morning.
