Look again at the README.Debian file. It doesn't pretend that the "right
db" should return the TAI time. It is the db to use if your hardware
clock is set to TAI, so that the returned time is correct.
The TAI time is currently 33 second ahead of UTC (10 seconds, plus the
23 leap seconds that have been added since 1972). That's why using the
"right" db, currently returns a time 33 seconds before the "posix" db.
