Hello, I have a list of names and a list of dates respective to each time that employee has participated in a certain event. I need another column to return the earliest event that employee has participated, or better yet, return a "1" in the row if that was the earliest event that employee has participated in. For example, the table below lists the employee name, the date of an event they participated in, and column C, which would be my expected result. For C2, formula would compare all dates respective to "Bill", then return a "1" if the date in that row was the earliest of all the events listed. Please help!

A________B________C
NAME____DATE_____EARLIEST?
Bill..........1/4/12..........0
Bill...........3/2/11.........1
Joe..........5/23/12.......0
Bob.........2/2/12..........1
Joe..........4/15/11........1
Bob..........6/12/12.......0
