Please believe me when I say that the only epoch worth discussing is 1970-01-01T00:00:00. This is the international UTC epoch (and oddly enough the Unix one as well). In order for a "number of seconds since some epoch" to be useful, the "epoch" must be the same for all calculations. This number will be consistent no matter what timezone you are in (which a floating epoch will not be). If you want to use "number of seconds since some specific second" subtract the epoch from your value to produce an offset.
