That's not quite true.  They had that many *TAI* seconds, but TAI seconds
are not equal to SI seconds.  TAI is an imperfect realisation of the
SI second.  UTC(TT) is a mildly interesting notion.

UTC ticked some 63072000.107757997 seconds in that time.  Of greater
relevance is that UTC ticked exactly 730 days (as you indicate).

So many nits to pick.
