Canon's 580EX manual and 580EX II manual state that normal flash duration (I am assuming at full power) is 1.2milliseconds (1/833 seconds) or shorter. Quick flash duration is 2.3milliseconds (1/434 seconds) or shorter. This is the most info I've seen from Canon. Shame on them for not providing more info.
