They perform an addition of 32.184 * Second, which differs from 32,184 s by approximately 2,5 fs, whereas the resolution of Instant a second from J2000 is a tenth of that.

operator""_UT1 is another can of worms entirely, but UTC and TAI being exactly related to TT(TAI), we should get that right; this could be fixed by adding those 184 milliseconds in DateTime arithmetic.
