Scheduling an event every day at a given time

Question

I want my event to run everyday at 00:20. I am confused in scheduling of the time. Should I be using the first option or the second one?

Option 1

CREATE EVENT my_event
  ON SCHEDULE
    EVERY 1 DAY
    STARTS '2014-04-30 00:20:00' ON COMPLETION PRESERVE ENABLE 
  DO
    # My query

Option 2

CREATE EVENT my_event
  ON SCHEDULE
    AT ('2014-04-30 00:20:00'+ INTERVAL 1 DAY) ON COMPLETION PRESERVE ENABLE 
  DO
    # My query
