No, because trying to track the sun that closely is a fools task in any case. Even at the dead center of a timezone the time of solar noon differs by a half an hour over the a year.

The leapsecond corrections are to keep an imaginary "mean" solar time in place. But this mean solar time is almost unphysical-- and not observable except through very fancy astronomy.

If you are actually interested in getting an accurate solar/astronomical time leapseconds are something of a hindrance, as you need to back them out to apply formula corrections and there isn't a general way to know if a recent leap second has actually been applied to your timebase (or double applied, or smeared or a spurious one applied...).
