I'd like to know the exact second (or even tenth of a second, but this isn't as necessary) that a shot is taken. The reason is I want to see how true the shutter actuations are to what interval I'm asking my 5DmIII to take them at during time lapse sequences. I've looked at the EXIF data in Finder on a mac, however neither "Get info" nor "More info" anything more exact than the minute of the exposure. Please let me know if I've overlooked a setting somewhere in the menu. Would prefer to avoid having to buy additional EXIF reading software if possible. In case a Magic Lantern user happens to browse this post, kindly advise if ML can provide me a solution here. I'm uninitiated. Thanks in advance.
