Add in the number of positive leap seconds, and subtract out the number of negative leap seconds, that have elapsed or that we *know* will elapse between the Epoch and the time in question. (Or am I missing something there.)
(No, this won't work if the "seconds-since-the-Epoch" value is far enough in the future and if the IERS ends up announcing an additional leap second or seconds before that point, but, well, *nothing*, other than a perfect lower-case-"o" oracle, will work in that case.)
This requires having the values from the "leapseconds" file around, but using them differently from the way the tz code uses them now.
