You'd have to subtract 86,400 seconds for each leap day that occurred on the Julian calendar that did not occur on the Gregorian calendar starting from the epoch. And your date's epoch has to be something that NSDate will understand, like either the Unix epoch (January 1, 1970) or Mac OS X epoch (January 1, 2001).
This, of course, means that you don't actually have to subtract anything until March 1, 2100...
